After https://crrev.com/c/5907583, handle_usage() tries to match the entire value. An allocation with usage 0x100000203 from BufferUsage::GPU_RENDER_TARGET | BufferUsage::CPU_READ_OFTEN | BufferUsage::FRONT_BUFFER would fail to match the combined BUFFER_USAGE_FRONT_RENDERING_MASK (`1U << 28 | 1ULL << 32`) because the allocation only sets a single usage bit `BUFFER_USAGE_FRONT_RENDERING` (`1ULL << 32`) and not the combined mask. Bug: b/373474508 Test: vts -m VtsHalGraphicsAllocatorAidl_TargetTest Change-Id: I926789a7aab937f2c2092475cb40ad9666b4f95f
