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)
```
