[Deploy] Change `numModules` type to `unsigned` (#74978)
Summary:
As it should never be negative, should it?
Also, add `torch/csrc/deploy` to the list of clang-format checked folders (as they are internally)
Last but not least: clang-tidy correctly identifies `totNumModules <= SIZE_MAX / sizeof(struct _frozen) - 1` as unneeded always true check (as `totNumModules` is int32, while SIZE_MAX is int64 and `sizeof(sturct_frozen)` is less than 4Gb ;) )
