Summary [ANGLE] Support BGRA_SRBGB_ANGLE for framebuffer blits

For WebGL content, WebKit needs to perform MSAA resolve on the WebGL buffer before compositing via a blit. On Apple platforms, this draw buffer is usually in BGRA8_SRGB_ANGLEX as it is the native format for the windowing system's compositor, so SRGB8_ALPHA8 needs coercion for WebGL to work with multisample sRGB content.
