gallium/u_blitter: enable MSAA when blitting to MSAA surfaces

If we're doing a Z -> Z MSAA blit (for example) we need to enable
msaa rasterization when drawing the quads so that we can properly
write the per-sample values.

This fixes a number of Piglit ext_framebuffer_multisample blit tests
such as ext_framebuffer_multisample/no-color 2 depth combined with
the VMware driver.

virgl: Clear the valid buffer range when possible

If we are discarding the whole resource, we don't care about previous contents,
and the resource storage is now unused, either because we have created new
resource storage, or because we have waited for the existing resource storage
to become unused, or because the transfer is unsynchronized.

In the last two cases this commit marks the storage as uninitialized, but only
if the resource is not host writable (in which case we can't clear the valid
range, since that would result in missed readbacks in future transfers).

In the first case, when the whole resource discard involves a reallocation, the
reallocation and subsequent rebinding already update the valid buffer range
appropriately.

As a side effect, we rework how vertex buffers are handled, duplicating

Adding the ability to link uniform blocks and shader storage blocks

linking was wrote with the names on its core.

The other major difference compared with the GLSL IR linker is that we
don't deal with layouts. There are no references to std140, std430,
etc. Layouts are expressed through explicit offset, array stride and
matrix stride. That simplifies how the buffer size are computed. But
also means that we couldn't use the existing methods at glsl_types, so
we needed to implement new methods.

It is worth to note that this linking do a iteration over the
glsl_types, similarly to what the linking uniforms do. A possible
future improvement would be refactor both cases to try to share more
