frameworks/native: fix copy back dirty region

Copyback dirty region logic does copyback,
even when its not necessary causing 2ms delay.
Fix the logic to copy back only what is necessary.

Support forcing all screenshots into a CPU consumer

Looks like a full GPU path is less efficient on some GPU
drivers that we're still using, and CPU is reliably faster...
(there's probably a locking condition going on somewhere, this
needs to be looked into)

Add support for QC's time_daemon

Enabled by BOARD_USES_QC_TIME_SERVICES=true, it requires the device
to provide its own time_daemon executable and libtime_genoff.so
proprietaries. The library should be copied by the device's setup
config to $OUT/obj/lib for linkage (and pushed to the final build,
obviously)
