clean: constexpr-ify and unify anon namespace use ( #4991 )
...
Constexpr guaranteed no runtime init in addition to const semantics.
Moving all opt/ to constexpr.
Moving all compile-unit statics to anonymous namespaces to uniformize
the method used (anonymous namespace vs static has the same behavior
here AFAIK).

* Switches to using enum classes with an underlying type to avoid
undefined behaviour

Handle propagation of arrays with decorations ( #4717 )
...
When copy propagating, OpDecorate instructions can be copied as is. For
array flattening, they should be ignored.

Add spirv-opt pass to replace descriptor accesses based on variable indices ( #4574 )
...
This commit adds a spirv-opt pass to replace accesses to
descriptor array based on variable indices with constant
elements.
Before:
```
%descriptor = OpVariable %_ptr_array_Image Uniform
...
%ac = OpAccessChain %_ptr_Image %descriptor %variable_index
(some image instructions using %ac)
```
After:
```
%descriptor = OpVariable %_ptr_array_Image Uniform
...
OpSwitch %variable_index 0 %case0 1 %case1 ...
...
%case0 = OpLabel
%ac = OpAccessChain %_ptr_Image %descriptor %uint_0
...
%case1 = OpLabel
%ac = OpAccessChain %_ptr_Image %descriptor %uint_1
...
(use OpPhi for value with concrete type)
```
