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.
