[SurfaceFlinger] Respect HDR data space.
Respect HDR data space when there is no legacy HDR support. Previously we only
cared about HDR data space when it is supported, however, on Pixel 2 there is
no HDR mode support. This patch makes sure that when HDR mode is not supported,
we fall back to Display P3 color mode correctly.
BUG: 80404330
Test: Build, flash and watch Youtube HDR
