Converted usage of CH-custom bit_cast to std::bit_cast if possible, i.e. when sizeof(From) == sizeof(To). (The CH-custom bit_cast is able to deal with sizeof(From) != sizeof(To).) Motivation for this came from #42847 where it is not clear how the internal bit_cast should behave on big endian systems, so we better avoid that situation as much as possible.
