v3dv: Add more supported formats to our format table

Some of these may need additional work to work for real, but we should
be able to support them.

We also include some formats that are not supported for images, but
that we want to support for buffers, such as R32G32B32 for a vertex
buffer.  In the future we might want to expand the format table to
specify which formats are supported for buffers.
