Subject: Support BufferHub-backed IGBP in libgui_test

Use gtest's TestWithParam tests to support testing both BufferQueue
backend and BufferHub backend. Testing against BufferHub backend is
gated by USE_BUFFER_HUB_AS_BUFFER_QUEUE build time flag, so that build
targets don't support BufferHub won't be impacted by this test.

Known issues:
b/36724099: Add support for BufferHubProducer::setAsyncMode(true)
b/38137191: Implement BufferHubProducer::detachBuffer
b/69981968: Implement BufferHubProducer::attachBuffer
b/70041889: BufferHubProducer need to support metadata: numPendingBuffers
b/70041952: BufferHubProducer need to support metadata: nextFrameNumber
b/73267953: Make BufferHub hornor producer and consumer connection

Bug: 68733388
Bug: 70046255
Bug: 73160000
Test: libgui_test
