[clang-linker-wrapper] Add ELF packaging for spirv64-intel OpenMP images (#125737)
Add manual ELF packaging for `spirv64-intel` images as there is no
SPIR-V linker available. This format will be expected by the runtime
plugin we will submit in the future and is compatible with the format we
already use downstream.
