c7ce8cd7f9 gpu: Fix context name parsing for non-null-terminated strings
Use String::from_utf8_lossy() instead of CStr::from_bytes_with_nul()
since the virtio-gpu driver sends debug_name without null terminator.

d9cabd8883 gpu: Add blob resource support
Implement blob resource support and shared memory mapping. This is required for
Venus support and gfxstream-{vulkan, gles} enablement.

9f72a8187f vhost-device-gpu: Refactor vhost-device-gpu
This commit refactors vhost-device-gpu by separating
virglrenderer from rutabaga, and using gfxstream via
rutabaga, Simplifying future backend development.

This commit introduces a significant refactor of the
virtio-gpu backend architecture:
- Transition `gfxstream` support to use `Rutabaga`
  abstraction.
- Decouple `virglrenderer` from `Rutabaga`, allowing
  it to be used as standalone.
- Unify backend handling using thread-local storage
  and macro-based runtime dispatch.

Key Changes:
VirglRenderer Backend:
   - `virgl.rs` is now a standalone backend that
     directly calls `libvirglrenderer` functions.
   - Removed reliance on `rutabaga` for virgl path.

Gfxstream Backend via Rutabaga:
   - Introduced `gfxstream.rs` backend using `rutabaga`
   - Thread-local `GfxstreamAdapter` manages its own
     `Rutabaga` instance, initialized lazily.
   - Preserved internal `GfxstreamResource` tracking
     with scanout support and memory handling.

Renderer Selection Logic:
   - In `device.rs`, `lazy_init_and_handle_event()` now:
     - Dispatches `VirglRendererAdapter` and
       `GfxstreamAdapter` using thread-local storage(TLS)
   - Introduced `extract_backend_and_vring()` helper for
     reusing backend setup logic.

Code Deduplication:
   - Abstracted common logic for both backends to common.rs.
   - Shared helpers reused between gfxstream and virgl.
   - Improved modularity with fewer duplicated error
     handling branches.

Testing and Validation:
   - Replaced `virtio_gpu.rs` testing paths with new unit
     tests for `gfxstream.rs` and `virgl.rs`.
   - Added code coverage for the new refactored crate.
   - Update coverage file to reflect the drop in coverage
     due to exclusion of some gfxstream tests from CI
     since they can't run in CI without GPU drivers.

02409f0a09 Move vhost-user-gpu from staging to main directory
The CLI interface should be stable now and coverage is good. Support
for more backends as described in the README is comming later.

Note that this decreases the test coverage in the staging directory from
82.43% to 74.62%.
