Add ImageFrame and GlTexture view providers to Ahwb GpuBuffer storage
- ImageFrame views are backed by CPU locks of the AHWB. - GlTextureViews are managed through a GlTextureBuffer connected to the AHWB allocation. This improves the latency of heterogeneous access sequences, but makes `ImageFrame > ImageFrame` sequences slower due to CPU locking. PiperOrigin-RevId: 481982546
