* Reland fuchsia external view embedder will be shared with platform view
This reverts commit 9b752790f4d25ab238576c719208d7a38c6293f3.
* wait for the external view embedder to be initialized before creating
shell
Additionally create "_next" permutations for all of the test binaries
on Fuchsia, in order to test both code-paths.
Using the #define follow-up CLs can also create a flutter_runner_next
binary that does not contain any legacy integration code.

This reverts commit a7a25d3b57f2066798ef8cd43600588e4697c9cd and relands our reland https://github.com/flutter/engine/pull/17915.
Additionally, we fixed the cull rect logic in `OpacityLayer::Preroll` which is the root cause of https://github.com/flutter/flutter/issues/56298. We've always had that root problem before but it did not trigger performance issues because we were using the OpacityLayer's `paint_bounds`, instead of its child's `paint_bounds` for preparing the layer raster cache. A correct handling of the cull rect should allow us to cull at any level.
It also turns out that our ios32 (iPhone4s) performacne can regress a lot
without snapping. My theory is that although the picture has a
fractional top left corner, many drawing operations inside the picture
have integral coordinations. In older hardwares, keeping those
coordinates integral seems to be performance critical.
To avoid flutter/flutter#41654, the snapping
will still be disabled if the matrix has non-scale-translation
transformations.
This reverts commit b5aedb3 and relands #17712.
Fixesflutter/flutter#53288 and flutter/flutter#41654.
Together with #17791, this reland addresses some of Jim's concerns in the original PR #17712.
The major part of this PR is still the same as the original PR, and the performance / golden image impacts should be the same.
This avoids the possible matrix mismatch between RasterCache::Get and
RasterCacheResult::draw. See
https://github.com/flutter/engine/pull/17790 for an example that tries
to fix an earlier mismatch.
This reverts commit 99f8d007aaefcf2cb0a0a40c0b3c6a6fd7556f5c.
I found some problems. Will revise and reland later, and put more details about the problems in the new PR.

This fixes https://github.com/flutter/flutter/issues/53288 and https://github.com/flutter/flutter/issues/41654. It removes the problematic `GetIntegralTransCTM`, but preserves the rect round-out in `RasterCacheResult::draw` for performance considerations: the average frame raster time doesn't change much but the worst frame raster time significantly regressed if rect round-out is removed. That's probably because a new shader needs to be compiled to draw raster cache with fractional offsets.
* [fuchsia] Add labels to Scenic nodes.
* [fuchsia] Skip creating Scenic nodes for identity Transforms.
* [fuchsia] Assign elevation to Scenic nodes based on paint order.
* [fuchsia] Create Scenic OpacityNodes at leaf nodes.
* [fuchsia] Composite PhysicalShapeLayers using Skia, except when they need to float above child views.
In that case, they will still need to be pulled
into separate Scenic nodes to be composited on top
of the child view[s].
* [fuchsia] Add tests for Fuchsia-specific layer behavior.
Inspect commands going to Scenic and make sure
they match what is expected.
Also, restructure code to need less member variables,
and other cleanups based on review feedback.
A previous version of this change also removed
system compositing of PhysicalShapeLayers on
Fuchsia. In this reland, keep using system
composting for PhysicalShapeLayers.

This adds more trace events to more layer operations and enhances the
trace counters for the Fuchsia vulkan surface pool to include retained
surface counts, emit stats on recycle events that might change the
surface count, and by separating counters which measure bytes from
counters which measure counts to make analysis simpler.
This is a duplicate of flutter/engine#13360 with the test switched to use the software backend instead of the GL backend.
After some debugging and testing on another GL embedder I think the issue with the test is some bug having to do with the GL implementation in the test harness specifically.
Fixesflutter/flutter#38903
Previously the cache was disabled on whether or not PlatformViews were
globally enabled. Instead track their existence in the view hierarchy
and only disable RasterCache if a PlatformView is actually present.

On Fuchsia, add a build flag for compositing OpacityLayers using the system
compositor vs Skia, which exposes a fastpath for opacity via Scenic.
This will only work under certain circumstances, in particular nested
OpacityLayers will not render correctly!
On Fuchsia, add a build flag for compositing PhysicalShapeLayers using
the system compositor vs Skia. Set to off by default, which restores
performant shadows on Fuchsia.
Remove the opacity exposed from ChildView, as that was added mistakenly.
Finally, we centralize the logic for switching between the
system-composited and in-process-composited paths inside of
ContainerLayer. We also centralize the logic for computing elevation
there. This allows the removal of many OS_FUCHSIA-specific code-paths.

* Fix broken tests
For https://github.com/flutter/flutter/issues/33807
We still need to make layers' children immutable for full immutability.
That will require us to change the SceneBuilder API to build the layer
bottom up instead of top down (post-order traversal instead of pre-order
traversal).
It ensures that every OpacityLayer can be optimized by retained
rendering.
Tested with `flutter test --local-engine=host_debug_unopt` in
flutter/flutter/packages/flutter.

This PR replaces the unused `PrerollContext::child_paint_bounds` with `PrerollContext::cull_rect` so we can prune unnecessary preroll tasks (especially cache) based on clips. This PR fixes https://github.com/flutter/flutter/issues/24712
Performance test has been added (https://github.com/flutter/flutter/pull/25381) to make sure that we won't regress again in the future.
Note that the cull_rect here is very similar to those removed in https://github.com/flutter/engine/pull/6352 . We can't compute cull rects in SceneBuilder because of retained layers. But we can still compute and use them to optimize performance in Preroll.
When the flag is true, we currently use a single thread configuration,
and disabled the raster cache for opacity layers.
The flag's name is 'io.flutter_embedded_views_preview'.
The overlay surfaces are going to be the same IOSSurface implementation
with the platform views controller set to null (so these are surfaces
that don't support embedding platform views to them).
* Adds a FlutterOverlayView which is a UIView that's showing an
overlay surface.
* Creates an overlay surface for each embedded UIView (done in
FlutterPlatformViewsController).
* Changes CompositeEmbeddedView to return a new canvas.
* Makes the PlatformViewLayer replace the PaintContext's canvas with
the canvas for the overlay view.
* Changed canvas in PaintContext to be a pointer so it can be changed.
TBD in following PRs:
* Copy the current canvas state when replacing a canvas in PaintContext.
* Make FlutterOverlayView work with a GL backend (currently it only
works with software rendering)
* Revert "Revert "Allow raster caching any layer subtree (#6442)" (#6506)"
This reverts commit c6e6da512a54c1bb33a584b117bcf300ce71b166.
* Use raw pointer for RasterCacheKey
So we won't depend on whether it's a std::unique_ptr or std::shared_ptr.
