Implement macOS wide gamut (Display P3) support ( #181769 )
...
Adds wide gamut color support to macOS (matching iOS), upgrades the
surface pixel format from 10-bit BGRA10_XR to 16-bit float RGBA16Float
on both iOS and macOS when enabled, and fixes Impeller's blur filter P3
clamping on macOS.
**macOS Wide Gamut Support**
- Added DoesHardwareSupportWideGamut() hardware capability check
(MTLGPUFamilyApple2 or MTLGPUFamilyMac2)
- Wide gamut enabled when both hardware supports it and
FLTEnableWideGamut plist flag is YES
- Dynamic wide gamut switching when windows move between P3 and sRGB
displays
- Added flutter/screenshot method channel on macOS for integration
testing
**RGBA16Float Surface Format (iOS + macOS)**
- macOS IOSurface: kCVPixelFormatType_64RGBAHalf +
MTLPixelFormatRGBA16Float
- iOS CAMetalLayer: MTLPixelFormatRGBA16Float
- Image decoder: always uses kRGBA_F16_SkColorType for all wide gamut
images (previously only transparent images used 16-bit)
**Fix Blur P3 Clamping on macOS**
macOS uses the compositor/embedder path, not GPUSurfaceMetalImpeller, so
UpdateOffscreenLayerPixelFormat was never called. Added the call in
embedder.cc after wrapping the Metal resolve texture.
**Why RGBA16Float over BGRA10_XR?**
BGRA10_XR has only 10 bits per channel — values outside sRGB gamut get
clamped in intermediate render targets (e.g. blur filters). RGBA16Float
has 16 bits per channel with full floating-point range, preventing P3
color clamping in multi-pass rendering.
**Tests**
- 9 new iOS FlutterView unit tests verifying RGBA16Float pixel format
and extended sRGB color space
- Updated macOS FlutterSurfaceManagerTest for RGBA16Float, dynamic
switching, color space, and pixel format verification
- Updated image decoder and Impeller display list tests for
kR16G16B16A16Float
- 11 macOS/iOS integration tests: image, saveLayer, codecImage, none,
blur, drawnImage, container, linearGradient, radialGradient,
conicalGradient, sweepGradient

Auto-format Framework ( #160545 )
...
This auto-formats all *.dart files in the repository outside of the
`engine` subdirectory and enforces that these files stay formatted with
a presubmit check.
**Reviewers:** Please carefully review all the commits except for the
one titled "formatted". The "formatted" commit was auto-generated by
running `dev/tools/format.sh -a -f`. The other commits were hand-crafted
to prepare the repo for the formatting change. I recommend reviewing the
commits one-by-one via the "Commits" tab and avoiding Github's "Files
changed" tab as it will likely slow down your browser because of the
size of this PR.

Relands "Wide gamut framework gradient test ( #153976 )" ( #157643 )
...
This was reverted because it failed to run. Colors were getting clamped
in the dithering fragment shader.
One change was made when relanding, i increased the epsilon for the
radial and conical gradients. They don't appear to give back the exact
color you asked for.
Do not land until https://github.com/flutter/engine/pull/56140 is rolled
into the framework.
