Previously, we were storing a pointer to the vtn_value because we use it
to look up decorations when we create input/output variables. This
works, but it also may be useful to have the id itself so we may as well
store that instead.

Now that higher levels are enforcing decoration sanity, we don't need
the vtn_asserts here. This function *should* be safe but we still want
a few well-placed regular asserts in case something goes awry.

This reworks the error checking on our generic handling of decorations.
The objective is to validate all of the SPIR-V assumptions we make
up-front and convert redundant checks to compiled-out asserts. The most
important part of this is to ensure that member decorations only occur
on OpTypeStruct and that the member is never out-of-bounds. This way
later code can assume that the member is sane and not have to worry
about OOB array access due to a misplaced OpMemberDecorate.

This is a bit simpler since we have fewer enum values in the case. It's
also a bit more efficient because we're making fewer glsl_get_* calls.
While we're at it, add better type validation.

Now that vtn_base_type is a real and full base type, we can switch on
that instead of the GLSL base type which is a lot fewer cases in our
switch.

Respect the std430 rules for determining offset and size of struct
members when using a std430 buffer. std140 rules lead to wrong buffer
offsets in that case.

This fixes a varying packing issue when using transform feedback in
GL_SEPARATE_ATTRIBS mode. By time we get to linking, we already
know that the number of feedback attributes is under the
GL_MAX_TRANSFORM_FEEDBACK_SEPARATE_ATTRIBS limit so packing isn't
as critical. In fact, packing/splitting vec3 attributes can cause
trouble because splitting effectively creates another TFB output
which can exceed device limits. So, disable vec3 packing when it's
not needed to avoid that issue.

The Talos Principle contains shaders with an OpSelect between two
vectors where the condition is a scalar boolean. This is technically
against the spec bout nir_builder gracefully handles it by splatting
out the condition to all the channels. So long as the condition is a
boolean, just emit a warning instead of failing.

Pointers with no storage type are converted to inout variables but SSA
values and pointers with a storage type (which turns into a uint or
uvec2) are just input variables.
Previously, we just gave them exactly the same type as the respective
image (which already had a sampler2D or similar type). Now they have
their own base type and a pointer to the vtn_type for the image.
