libc++: Revert some patches

* `27-bitset.patch`: `__SIZEOF_SIZE_T__` is used in ([src/filesystem/error.h](https://github.com/ytsaurus/ytsaurus/blob/main/contrib/libs/cxxsupp/libcxx/src/filesystem/error.h)), hence the initial statement from rXXXXXX is no longer relevant
* `48-version.patch`: This instance of libc\+\+ is not compiled with MSVC anymore, hence `# if defined(_MSC_VER) && _MSC_VER >= 1926` patches are irrelevant.
* `50-operations.patch`: This should be handler by `NO_COMPILER_WARNINGS()` in `ya.make`
