Created HardwareBufferRenderer to support rendering into
HardwareBuffer targets.
Relnote: "Created HardwareBufferRenderer API to handle
rendering a single frame into a HardwareBuffer target."
Refactored dlsym logic for dynamically resolving AHardwareBuffer
methods to be shared across multiple locations.
Bug: 255692581
Test: Created HardwareBufferRendererTests
