frameworks/native: Modify dirtyRect only on GPU pre-rotation.

Modify layer dirtyRect only when the buffers are pre-rotated by
GPU, not when the buffers are scheduled to be rotated during
composition.

sf: Fix incorrect state reporting in dumpsys

Dumpsys utility access layer compositionType variable
with out proper protection. These variables are modified
during hwc_prepare call. Existing HAL lock protection is not
sufficient to address this issue. Failure to do this will
result in incorrect state reporting in dumpsys.

A new drawLock mutex in HWComposer that will be used in both
dumpsys and draw calls to ensure correct state is accessed.

sf: Enable GPU Tiled DR optimization for overlap and mixed mode use cases

Extend the GPU Tiled DR optimization to Overlapping layers use cases
and mixed mode composition.

Binder: Resolve race condition

The transaction buffer does not be freed before sendReply,
which may result in the next command fails. e.g. If one
application immediately creates another player to play next
video clip after releases the previous one, the setup may
fail for the native player does not be freed and the surface
is still connected to the previous one.

SF: Check ViewFrame validity before sending to hwc

Check if ViewFrame is valid before sending to hwc to make sure
composition produces valid values.

A ViewFrame can get invalid values when the framework is disconnected
which is a step necessary for some testing scenarios.

sf: Clear FrameBuffer only if there are GLES composed layers

Clear FrameBuffer Target only if there are layers to be composed by
GLES. Otherwise, it results unnecessary gl calls and increases power
consumption in full MDP comp use cases.
