rhine-common: Omni-fy
rhine-common: Add ril_msim.h

Omni doesn't have mSIM support in the framework yet, but Sony Qualcomm devices run their own
libril which depends on the header. Add it to satisfy build requirements until mSIM support
can be properly integrated into Omni.
rhine-common: Comment out TW_BOARD_CUSTOM_GRAPHICS

The file is outdated and obsolete, using graphics.c from mainline TWRP should be just fine.
Rhine-common: Fix up TWRP

- Use RGB_565 instead of RGBX_8888
- Update twrp.fstab
- Delete twrpgraphics.c (Now obsolete)
- Actually copy twrp.fstab to the right directory. Derp.
rhine-common: Modify custombootimg.mk to work with Omni kernel defconfigs
Rhine-common: Delete camera2 overlay

EnableZSL is for Samsung ZSL on Omni, and it was preventing preview from working correctly.
rhine-common: Change dtbTool name
Rhine-common: Audio improvements

- Enable low latency audio
- Enable gapless playback
- Fix up a typo, preventing voice call props to be copied properly
