  [MLIR][SPIRV] Deduce Shader capability for DescriptorSet/Binding decorations (#188743)

UpdateVCEPass only queried capabilities via QueryCapabilityInterface and
SPIRV type capabilities, but did not check capabilities implied by
decoration attributes on ops. Specifically, the DescriptorSet and
Binding decorations—represented by the `binding` and `descriptor_set`
attributes on `spirv.GlobalVariable`—require the `Shader` capability per
the SPIR-V spec Decoration table, but this was not deduced.

Add an explicit check in UpdateVCEPass: when a `spirv.GlobalVariable`
has a `binding` or `descriptor_set` attribute, require the `Shader`
capability.

Part of #168357
