Subject: [PATCH] Add WAKEUP_SURFACE_FLINGER permission

Add a new permission so sysui and launcher can provide
a hint to SurfaceFlinger to wake up earlier via
eEarlyWakeupStart  & eEarlyWakeupEnd transaction flags.
The flags can be used to indicate the composition is likely to
be expensive (blur, corners, etc).

Test: presubmit
Fixes: 261103978
