Before, we were calculating up-front and then filling in later. Now we
just grow as needed in anv_nir_apply_pipeline_layout.

This moves us away to the array of pointers model and onto a model where
each param is represented by a generic uint32_t handle. We reserve 2^16
of these handles for builtins that get generated by somewhere inside the
compiler and have well-defined meanings. Generic params have handles
whose meanings are defined by the driver.
The primary downside to this new approach is that it moves a little bit
of the work that we would normally do at compile time to draw time. On
my laptop this hurts OglBatch6 by no more than 1% and doesn't seem to
have any measurable affect on OglBatch7. So, while this may come back
to bite us, it doesn't look too bad.

This allows shaders to write to storage images declared with unknown
format if they are decorated with NonReadable ("writeonly" in GLSL).
Previously an image view would always use a lowered format for its
surface state, however when a shader declares a write-only image, we
should use the real format. Since we don't know at view creation time
whether it will be used with only write-only images in shaders, create
two surface states using both the original format and the lowered
format. When emitting the binding table, choose between the states
based on whether the image is declared write-only in the shader.
Tested on both Sascha Willems' computeshader sample (with the original
shaders and ones modified to declare images writeonly and omit their
format qualifiers) and on our own shaders for which we need support
for this.

This makes our driver robust to changes in spirv_to_nir which would set
this flag on the variable. Right now, our driver relies on spirv_to_nir
*not* setting var->data.image.write_only for correctness. Any patch
which implements the shaderStorageImageWriteWithoutFormat will need to
effectively revert this commit.

This way the the bind map (which we're caching) is mostly independent of
the pipeline layout. The only coupling remaining is that we pull the array
size of a binding out of the layout. However, that size is also specified
in the shader and should always match so it's not really coupled. This
rendering issues in Dota 2.

nir_instr_rewrite_src() expects a nir_src and it is currently being fed a
nir_tex_src. This will crash something.
