Camera2: Add native test for framework-backed ZSL

The test needs to make sure that all
necessary requirements for enabling the
framework-backed ZSL mode along the
API1->HAl3.x path are fulfilled. It should
then go through all supported picture
resolutions and try to take still
images in such conditions, that will
allow ZSL to remain active and process
frames from its own internal queue.
