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.

native: Make setting the buffers size conditional to qualcomm hardware

This is a partial ifdef of CAF commit d6eecf50919312c1dd778c5742de72bb98f98f1a.

Some devices might have proprietary bits that link against libgui/libui components
and are not expecting the ABI mismatch introduced in that commit.

sensorservice: add fusion sensors if all events are supported

- Fusion sensors depend on gyro, mag field, and accelerometer
  events in order to emulate these sensors.  Don't create
  them unless ALL of the real hardware devices required exist.
