[WebXR] Override compositor textures sRGB transfer function
https://bugs.webkit.org/show_bug.cgi?id=273603
rdar://127400068
Reviewed by Mike Wyrzykowski.
Immersive VR sessions in WebXR look washed out compared to the inline version.
CompositorServices provides textures with pixel format
MTLPixelFormatBGRA8Unorm_sRGB. Since glBlitFramebuffer is implemented as a draw
in ANGLE, when blitting shared to layered layout an unwanted gamma conversion is
being applied which is resulting in "lighter" than expected values.
To fix this, override the format with GL_BGRA8_EXT (aka
MTLPixelFormatBGRA8Unorm) when attaching the compositor images as external
images to avoid this conversion.
