[SurfaceFlinger] Add getCompositionPreference APIs to SurfaceComposer.
Previously we added APIs in ConfigStore to return the composition data space
and pixel format that SurfaceFlinger would prefer for the device. This patch we
plumb such information up to SurfaceComposer to prepare HWUI to use it to
render.
BUG: 113530681
Test: Build, flash, boot and verified the output in adb logcat.
