fabrizio-indirli b95dfa3920 [mlir][spirv] Fix LowerABIAttributesPass to generate EntryPoints for SPV1.4 (#118994) ...

- Extend the SPIRV::LowerABIAttributesPass to detect when the target env
is using SPIR-V ver >= 1.4, and in this case add all the functions'
interface storage variables to the spirv.EntryPoint calls, as required
by the spec of OpEntryPoint:
"_Before version 1.4, the interface’s storage classes are limited to the
Input and Output storage classes. Starting with version 1.4, the
interface’s storage classes are all storage classes used in declaring
all global variables referenced by the entry point’s call tree_."
- Fix: generate the replacement ops (spirv.AddressOf and .AccessChain)
in the order in which the associated variable appears in the function
signature
