LOG: [SPIR-V] Built-in variables: mapping from an OpenCL to SPIR-V BuiltIn and SPIR-V friendly builtins for Image Read/Write instructions (#127242)
This PR improves built-in variables and functions support:
* extends mapping from an OpenCL C built-in function to the SPIR-V
BuiltIn variables as in
https://registry.khronos.org/OpenCL/specs/3.0-unified/html/OpenCL_Env.html#_built_in_variables,
and
* adds SPIR-V friendly builtins for Image Read/Write instructions.
Test cases are extended accordingly.
