Handle suballocated AHB buffers

VkBuffers backed by AHBs do not require dedicated allocations.
As such, update SupportsAllocateInfo() to report supported as
long as a VkImportAndroidHardwareBufferInfoANDROID or a
VkExportMemoryAllocateInfo with AHB bit was found.

Updates allocateAndroidHardwareBuffer() to treat the lack of a
dedicated buffer or image as a request to allocate a blob AHB.
