For the NIR XFB gathering as well as all the Vulkan drivers, buffer
strides in nir_xfb_info are in bytes. When Marek started using
nir_xfb_info for GLSL on radeonsi, he copied directly from the GLSL
struct which has strides in dwords. This inconsistency didn't show up
until I went through and started us using the NIR passes for GL drivers
directly without going through the GLSL structs. We could change the
nir_xfb_buffer_info field to be in dwords to be consistent with
shader_info but that would mean changing all the Vulkan drivers but, for
now, it's easier to always use bytes in nir_xfb_info.

A lot of the fields get fully overwritten but outputs/buffers_written
are both bitfields that we set one bit at a time.

This saves a lot of pointless gl.h includes across the board,
it moves the one place that needs GLenum into a separate file
only used in those passes that require it.

This just adds the structure with a name and its update function.
strlen and others will be added in the following commits. The idea is to
parse and analyze the name in advance to make glGetUniformLocation faster.

Several files had a initial comment about the purpose of such files,
including a reference that the NIR linker was implemented with just
ARB_gl_spirv in mind.
Since the nice job Timothy is doing to use the NIR linker on GLSL,
that is not true anymore, so let's remove that reference and also
tweak some other comments.

When varyings was added we moved to use to dynamycally allocated
pointers, instead of allocating just one block for everything. That
breaks some assumptions of some vulkan drivers (like anv), that make
serialization and copying easier. And at the same time, varyings are
not needed for vulkan.
So this commit moves them out. Although it seems a little an overkill,
fixing the anv side would require a similar, or more, changes, so in
the end it is about to decide where do we want to put our effort.
v2: (from Jason review)
* Don't use a temp variable on the _create methods, just return
result of rzalloc_size
* Wrap some lines too long.

From the ARB_enhanced_layouts specification:
"For the property TRANSFORM_FEEDBACK_BUFFER_INDEX, a single integer
identifying the index of the active transform feedback buffer
associated with an active variable is written to <params>. For
variables corresponding to the special names "gl_NextBuffer",
"gl_SkipComponents1", "gl_SkipComponents2", "gl_SkipComponents3",
and "gl_SkipComponents4", -1 is written to <params>."
We were storing the xfb_buffer value, instead of the value
corresponding to GL_TRANSFORM_FEEDBACK_BUFFER_INDEX.
Note that the implementation assumes that varyings would be sorted by
offset and buffer.

Instead of a custom ARB_gl_spirv xfb gather info pass.
In fact, this is not only about reusing code, but the current custom
code was not handling properly how many varyings are enumerated from
some complex types. So this change is also about fixing some corner
cases.
