[HWUI] Implement legacy color mode.

Previously, HWUI always produces SRGB buffers. We introduced new APIs for
SurfaceFlinger, a.k.a. the composer service to return to composition preference
for data space, and pixel format. This patch makes HWUI query composition
preference from composer service, and creates the corresponding EGL surface
with the correct attributes.

In legacy mode, HWUI will take the pixel value from source color space, and
interpret it as pixel value in destination color space.

BUG: 111436479
BUG: 113530681
Test: Build, flash, boot and check dumpsys SurfaceFlinger
