Fix Droid and animation color in recovery mode

[Problem]
Droid and animation color in recovery mode are incorrect

[Modify]
- Add support for flipping (zero copy) with RECOVERY_ABGR.
- Decodes PNG files to BGRA directly, and other fills, text and alpha blending are also done directly in BGRA (i.e. blits can still bypass conversion)
- Remove the BGRA workaround added previous for single buffer mode (f766396)
