[libclang/python] Renaming get_version into get_clang_version (#188515)

Rename `get_version` to `get_clang_version` to match the `libclang.so`
name[1], and be clear we doesn't return some `cindex.py` internal
versioning but the `libclang.so` one.

[1] This match was some current API are doing for example
`conf.lib.clang_getArraySize` is mapped to `get_array_size`.
