vc4: Upload CS/VS UBO uniforms together.

Same as I did for V3D, drop all this code trying to GC the
non-indirectly-loaded uniforms from the UBO that's used for indirect
access of gallium cb[0].  While it does successfully drop some of those,
it came at the cost of uploading the VS's indirect unifroms twice, for the
bin and render versions of the shader.

With the UBO loads simplified, I was also able to easily backport V3D's
change to pack a UBO offset into the uniform_data[] field so that we don't
need to do the add of the uniform base in the shader.

As a bonus, now vc4 doesn't depend on mesa/st type_size functions.

st: Lower uniforms in st in the !PIPE_CAP_PACKED_UNIFORMS case as well.

PIPE_CAP_PACKED_UNIFORMS conflates several things: Lowering uniforms i/o
at the st level instead of the backend, packing uniforms with no padding
at all, and lowering to UBOs.

Requiring backends to lower uniforms i/o for !PIPE_CAP_PACKED_UNIFORMS
leads to the driver needing to either link against the type size function
in mesa/st, or duplicating it in the backend.  Given that all backends
want this lower-io as far as I can tell, just move it to mesa/st to
resolve the link issue and avoid the driver author needing to understand

We have other clues, though:

- On one side, dEQP-VK.texture.explicit_lod.* tests fail when using 4
bits, but work when using 8 bits. These tests try to mimic the expected
behaviour as much real as possible, and they use the reported
subTexelPrecisionBits and mipmapPrecisionBits reported to get this.

- On the other side, the equivalent driver for Windows is reporting 8
bits for both elements. Not sure if they got to verify it from the PRM
or from a diffent source.

glsl/linker: location aliasing requires types to have the same width

From the OpenGL 4.60.5 spec, section 4.4.1 Input Layout Qualifiers,
Page 67, (Location aliasing):

  " Further, when location aliasing, the aliases sharing the location
    must have the same underlying numerical type and bit
    width (floating-point or integer, 32-bit versus 64-bit, etc.) and
    the same auxiliary storage and interpolation qualification."

Additionally, we have improved the linker error descriptions.
Specifically, when taking structs into account we were producing a
linker error because we assumed that all components in each location
were used and that would cause component aliasing. This is not
accurate of the actual problem. Now, the failure specifies that the
underlying numerical type incompatibility is the cause for the
failure.

Fixes the following piglit test:

tests/spec/arb_enhanced_layouts/linker/component-layout/vs-to-fs-width-mismatch-double-float.shader_test

v2:
  - Do not assert if we see invalid numerical types. These come
    straight from shader code, so we should produce linker errors if
    shaders attempt to do location aliasing on variables that are not
    numerical such as records.
  - While we are at it, improve error reporting for the case of
    numerical type mismatch to include the shader stage.

v3:
  - Allow location aliasing of images and samplers. If we get these
    it means bindless support is active and they should be handled
    as 64-bit integers (Ilia)
  - Make sure we produce link errors for any non-numerical type
    for which we attempt location aliasing, not just structs.

v4:
  - Rebased with minor fixes (Andres).
  - Added fixing tag to the commit log (Andres).

v5:
  - Remove the helper function and check individually for the
    underlying numerical type and bit width (Timothy).
  - Implicitly, assume that any non-treated type which is checked for
    its underlying numerical type is either integer or
    float and has a defined bit width (Timothy).
  - Implicitly, assume that structs are the only non-treated
    non-numerical type (Timothy).
  - Improve the linker error descriptions and commit log (Andres).
