gpu_renderer: add virglrenderer bindings

These bindings are needed for virtio-gpu 3D capabilities.

All the rust files under gpu_renderer/src/generated are generated via
the gpu_renderer/src/generated/generate script.

The gpu_renderer/src/lib.rs file contains the Renderer and Context
structs, which are the main interfaces to virglrenderer. They
encapsulate the global state of virglrenderer (Renderer) and each
context ID (Context).

The command_buffer module is included only for basic testing and is not
intended for production use.

The pipe_format_fourcc module is provided for the conversion of
virglrenderer specifc formats to standard fourcc formats.
