This also adds a function to demangle a symbol, and a way for the backtracing code to report warning messages to the same place as the main runtime. I'd like to rename the _swift_isThunkFunction() SPI also, but we can't do that until we've made the changes to the _Backtracing library, so we'll do that there instead. rdar://110261430

If you're wondering where the tests are, I left them until the last PR (#66338) so everything was enabled and they'd actually work. |

Mike and Max made various helpful suggestions, so I've added and updated various comments and amended the code to cope with partial reads and writes. rdar://110261430
Moved the comment for `_swift_backtrace_demangle` into the header file instead of it being in the implementation. rdar://110261430
