surfaceflinger: add BT2020_PQ support to RenderEngine
Add Key::Y410_BT2020_ON which performs Y410/BT2020 YUV -> RGB
conversion.
Add Key::{INPUT,OUTPUT}_TF_ST2084 which performs ST2084 EOTF and
OETF conversions.
Add Key::TONE_MAP_ON which performs tone-mapping.
Flip proper bits on when the source buffer has BT2020_PQ as its
dataspace. That means,
1. convert YUV to RGB
2. apply ST 2084 EOTF
3. apply tone-mapping
4. convert to DisplayP3
5. apply relative rendering intent (i.e., clamp)
6. finally apply sRGB OETF
We still use hardcoded parameters rather than the ones from HDR
metadata. It is also likely that we will need to switch to a LUT
for better perf.
