This is slightly modified version of another patch originally created by David Stevens (stevensd@chromium.org), but since reverted. https://chromium-review.googlesource.com/c/chromiumos/platform/minigbm/+/3256451 Use blob buffers for ABGR8888 format buffers. This is necessary on ARCVM to mitigate a performance problem with the `testSurfaceTransaction_setEnableBackPressure` test from the `CtsViewTestCases`, as the test expects to be able to read back rendered buffers at 60fps. Almost all the code is the same, with the only differences (besides some minor conflict resolutions resurrecting this patch) being in the switch statement in `should_use_blob` in `virtgpu_virgl.c` where a check for ABGR8888 is added. The rest of the change is as authored by stevensd@, which requires knowing the host buffer layout before creating the blob resource, and using an LRU cache of layouts to avoid the overhead of querying the host every time a buffer is created. As noted in stevensd@'s CL, virgpu_cross_domain will be the preferred replacement to virgpu_virgl, and which is expected to have better performance without this kludge.
