CORE: Use uint64_t for bitmap configs

[andylin-hao]

What

Make the bitmap-type config profile_mode uint64_t to align with recent UCX(S) changes.

Why ?

UCX(S) now uses uint64_t for bitmap-type (declared via UCS_CONFIG_TYPE_BITMAP) configurations (see openucx/ucx@8a84af8). UCC should align with this change, otherwise setting bitmap-type config may overwrite the next 4-byte memory during config parsing (see openucx/ucx@8a84af8#diff-8dd28fc04f39623f32e719552443482db8a07986754b3ba0ba48387db94d8bbdL446). In the case of UCC, the profile_file option of ucc_global_opts will be overwritten when profile_mode is set.

@andylin-hao Thanks. Which org do you represent?

[andylin-hao]

@manjugv Hi, I'm currently a PhD student (https://github.com/andylin-hao) researching on GPU communications. Just came across this problem when researching UCC/X out of curiosity. So I'm not really representing any specfic orgs in this case, though my official affiliation is with Tsinghua University.

@andylin-hao Will you be able to sign a CLA? [1] Without that, we cannot accept the change.
