This is manual roll because dart_boringssl_gen_rev is no longer present
in dart sdk DEPS has to be removed from flutter engine DEPS manually.
Reverts flutter/engine#54453
Not quite ready to remove Impeller Scene yet because I'm still porting
the animation functionality. Keeping it around allows me to switch back
and forth to compare without having to recompile the engine.
Over a month ago I said something like "we can revert this a couple of
weeks from now" in one of the Impeller meetings. But for better or worse
(better, I think), I ended up spending a ton of time trying to make the
PBR good first (which doesn't exist in this C++ version).
Since gen_snapshot is lipo'd everywhere now, it should be safe to both
build with either arm64 or intel macs, and to use the arm64 native clang
toolchain on arm64 macs instead of the intel toolchain under Rosetta.

This PR does a few things. Mainly it makes the builds in
mac_host_engine.json each build fewer targets to increase parallelism
for post-submit and release builds. To ensure that increasing
parallelism doesn't lead to capacity issues, this change also allows the
mac_host_engine.json builds to run on either intel or arm64 macOS hosts.
Finally, when building on an arm64 macOS host to target macOS, this PR
changes the `gn` script to ensure that the arm64 native clang toolchain
will be used.
To keep mac_host_engine.json focused on builds that produce artifacts,
this PR also moves tests from that file into the ill-named
mac_unopt.json. In a subsequent PR, I'll rename all the *_unopt.json
files to *_tests.json or something similar.
The artifacts produced by these builds are passing framework presubmit
checks in https://github.com/flutter/flutter/pull/152345.
We don't support 32-bit arm iOS builds anymore. But adding the --ios-cpu=arm64 appends the "_arm" to the out subdirectory. This just causes confusion since the ios_debug_unopt is still arm64.
Just remove the flag that does nothing.
This flag as originally introduced to see if it made the GN step slower. It did not do so in any measurable manner and the default was flipped to true. AFAICT, no one disables and its good to have tracelogs to debug GN slowdowns. Remove the flag.
Removes impeller_capture, impeller_use_prebuilt_impellerc, impeller_use_prebuilt_scenec, and impeller_trace_canvas.
Also removes setting these flags from ./flutter/tools/gn.
The size of the LTO build of the engine with the dylib compressed is as follows:
```sh
$ du -k libFlutter*
5236 libFlutter.dylib.tar.gz
4324 libFlutterSlimpeller.dylib.tar.gz
```
Sizes are in KiB. This represents a binary size reduction of 17.41% of the compressed artifacts. The compression ratios will likely differ based on the compression scheme.
Uncompressed, the sizes are:
```sh
$ du -k libFlutter*
16920 libFlutter.dylib
14044 libFlutterSlimpeller.dylib
```
This represents a binary size reduction of 16.99% which is in the same ballpark.
The really mucky bit was backing out the raster cache and persistent cache. I want to clean that up in a later patch so that those TUs are part of a separate submodule.
Opting out of Impeller will lead to a fatal log at startup saying the opt-out is disallowed.
Fixes https://github.com/flutter/flutter/issues/126606
This PR changes from using a different GN pool for each non-compiler tool, to using one GN pool for everything.
Additionally, since we are no longer linking remotely in any configuration, this PR uses the pool for linking.
ObjC and impellerc tasks also do not (yet) run on RBE, so they are also now governed by the pool.

This removes goma most places except for the arguments to the `gn`
script, which are referenced by recipes. This does not remove goma
capabilities from the GN build entirely. That requires changes in the
buildroot which have to be staged after this change.
The Dart -> Flutter Engine autoroller seems to be failing atm due to
fuchsia build errors.
The Dart SDK CL in [0] is depending on a fuchsia gn sdk import. The
import path defaults to `//third_party/fuchsia/gn-sdk` in the Dart build
rules.
Though flutter seemingly has it in `//flutter/tools/fuchsia/gn-sdk`
(which was added to DEPS in c274921fa6034e5e133129967c0789ab8c7fc827)

Currently, these scripts run on each invocation of `gn`, and can take
many seconds to run.
This PR shifts them to run as `gclient` hooks instead, so that `gn` will
be faster.
Needs https://github.com/flutter/buildroot/pull/825.
Fuchsia team is working on getting rid of non-versioned libraries and sysroot (see b/40935282), but flutter is using a fairly old version of in-house gn-sdk. It's hard to maintain it anymore.
So this change removes the in-house gn-sdk and replaces it with the gn-sdk from chromium.
This is a prerequisite to select the idk / sdk lib version according to the api-level.
This change contains three parts:
1) Replacing gn-sdk/ with gn-sdk/src/ since the chromium needs a README.chromium in gn-sdk/ folder.
2) Making the existing build rules work with the newer gn-sdk.
3) Drive-by replacing "gtest_runner.shard.cml" with "sys/testing/gtest_runner.shard.cml", it's in fuchsia sdk already.

Unlike Goma, the local RBE server must be manually started and stopped
between each `ninja` build.
This PR adds the startup and shutdown before and after `ninja` is run in
the build config runner. It also removes the RBE startup logic from the
`gn` script, which was the wrong place for it since there was no
opportunity for it to shutdown the service. Removing this logic from the
`gn` script will not affect CI since the recipes already do the right
startup and shutdown, and logic in the `gn` script skipped the now
deleted section of code.

Original Description:
This PR refactors the RBE build and adds support for mac-hosted builds to use RBE. In particular, configurations files are downloaded from flutter-internal CIPD instead of being included in the repo. The download from CIPD is triggered by the presence of the `use_rbe` flag as a custom var in the `.gclient` file.
This PR also turns on RBE for Linux and macOS builds that do not produce artifacts.

The new `BUILD.gn` files in the Engine tree can't go under
`build/secondary` because Skia still has its own, and they'd be selected
first. So, this PR puts the new `BUILD.gn` files under `flutter/skia`.
Instead, this PR copies the frontend server from the Dart SDK (whether prebuilt or not) into the location expected by internal engine tests and artifact construction. This PR also consolidates the three GN templates that invoked the frontend server down to one.
