cbda72a5 - [NFC][libclc] Merge atomic extension built-ins with identical name into a single file (#134489)

[NFC][libclc] Merge atomic extension built-ins with identical name into a single file (#134489) llvm-diff shows there is no change to amdgcn--amdhsa.bc. Similar to how cl_khr_fp64 and cl_khr_fp16 implementations are put in a same file for math built-ins, this PR do the same to atom_* built-ins. The main motivation is to prevent that two files with same base name implementats different built-ins. In a follow-up PR, I'd like to relax libclc_configure_lib_source to only compare filename instead of path for overriding, since in our downstream the same category of built-ins, e.g. math, are organized in several different folders.
