spirv: Use nir_const_value for spec constants

When we originally wrote spirv_to_nir we didn't have a good scalar value
union to handily use so we rolled our own thing for spec constants.  Now
that we have nir_const_value, we can use that and simplify a bunch of
the spec constant logic.

anv/radv: Resolving 'GetInstanceProcAddr' should not require a valid instance

Since vk_icdGetInstanceProcAddr() is wired through
vkGetInstanceProcAddr() in both drivers, we lost the ability for
'GetInstanceProcAddr' to resolve itself prior to having a valid
instance.

An upcoming spec change will fix that and allow
vkGetInstanceProcAddr() to resolve itself passing NULL as
instance. See https://gitlab.khronos.org/vulkan/vulkan/issues/2057
for details.

This patch implements the change in both radv and anvil.

meson: correct windows-version define

The macro "_WINVER" does nothing, the macro definitions that matter for
windows API version selection are "_WIN32_WINNT" and "WINVER".

The header "sdkddkver.h" (which is included from thousands of
different windows-headers) defines "WINVER" to the same value as
"_WIN32_WINNT" of only the latter is defined, which explains why this
works right now. But we shouldn't depend on that kind of luck, and
instead define the right maco.

nir: Actually do load/store vectorization beyond vec2

nir_opt_load_store_vectorize has an is_strided_vector() function that
looks for types with weird explicit strides.  It does so by comparing
the explicit stride against the type-size-derived typical stride.

This had a subtle bug.  Simple vector types (vec2/3/4) have no explicit
stride, so glsl_get_explicit_stride() returns 0.  This never matches the
typical stride for a vector, so is_strided_vector() would return true
for basically any vector type, causing the vectorizer to bail.

I found this by looking at a compute shader with scalar SSBO loads at
offsets 0x220, 0x224, 0x228, 0x22c.  nir_opt_load_store_vectorize would
properly vectorize the first two into a vec2 load, but would refuse to
extend it to a vec3 and ultimately vec4 load because is_strided_vector()
saw a vec2 and freaked out.

Neither ACO nor ANV do load/store vectorization before lowering derefs,
so this shouldn't affect them.  However, I'd like to fix this bug to
avoid the trap for anyone who decides to in the future.  In a branch
where anv used this lowering, this cut an additional 38% of the send
messages in the shader by properly vectorizing more things.
