Fixed C preprocessor macros in image.cl to generate proper Itanium C++
ABI mangled names with substitution references (S0_) for repeated vector
types in SPIR-V bindless image array functions.
Previously, libclc-remangler undocumentedly corrected Itanium C++ ABI
violations. Now new symbol names match SYCL frontend output directly,
eliminating the need for libclc-remangler correction.
Example for __spirv_ImageArrayWrite<ulong, vec2<int>, vec2<int>>:
Before: _Z23__spirv_ImageArrayWriteImDv2_iDv2_iEvT_T0_iT1_
^^^^^ ^^^^^ - both spelled out
After: _Z23__spirv_ImageArrayWriteImDv2_iS0_EvT_T0_iT1_
^^^ - second uses S0_
