Subject: Verify SurfaceView BlastBufferQueue behavior

Initial code to easily configure buffer producers to generate buffers
with different properties inorder exercise and validate
BlastBufferQueue adapter.

The test captures surface flinger traces and verifies properties of a
single buffer. This will allow us to verify buffer presentation order,
buffer rejection, buffer properties and so on.

Test: atest SurfaceViewBufferTests
Bug: 168504870
Change-Id: I9714d7b6f5ffbe5fecca5d93e8184f0e6ac2b4c1
