Format RPC files with clang-format (#50367)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/50367
This had already been done by mrshenli on Friday (#50236, D25847892 (https://github.com/pytorch/pytorch/commit/f9f758e3497b357668c2a259ea070bb33c591a0b)) but over the weekend Facebook's internal clang-format version got updated and this changed the format, hence we need to re-apply it. Note that this update also affected the JIT files, which are the other module enrolled in clang-format (see https://github.com/pytorch/pytorch/commit/8530c65e2560c5a5d464a5e21a70b42fb8469b6d, D25849205 (https://github.com/pytorch/pytorch/commit/8530c65e2560c5a5d464a5e21a70b42fb8469b6d)).
