Jonas Toth 8ba28c7200 [clang-tidy] Fix bug 34845, offending standard bitmask types
Summary:
The C++ standard allows implementations to choose the underlying type for
bitmask types (e.g. std::ios_base::openmode). MSVC implemented some of them
as signed integers resulting in warnings for usual code like
`auto dd = std::ios_base::badbit | std::ios_base::failbit;`

These false positives were reported in https://bugs.llvm.org/show_bug.cgi?id=34845

The fix allows bitwise |,&,^ for known standard bitmask types under the condition
that both operands are such bitmask types.
Shifting and bitwise complement are still forbidden.
