Support AHARDWAREBUFFER_FORMAT_BLOB buffers

by mapping BLOBs to `Buffer`s instead of `ColorBuffer`s and by
adding the needed plumbing for reads and updates.

Note: this is not a fully complete solution as technically a
guest not running with ANGLE could still have native Vulkan
users which import the BLOB AHBs. This has not yet been observed
so this might be okay for now.

Bug: b/234513607
Test: launch_cvd --gpu_mode=gfxstream (with WIP ANGLE)
Test: cts -m CtsNativeHardwareTestCases
Test: ANGLE's `ExternalBufferTestES31.*/ES3_1_Vulkan` tests
