[ASTMatchers] Output currently processing match and nodes on crash

Create a PrettyStackTraceEvent that will dump the current `MatchCallback` id as well as the `BoundNodes` if the 'run' method of a `MatchCallback` results in a crash.
The purpose of this is sometimes clang-tidy checks can crash in the `check` method. And in a large codebase with alot of checks enabled and in a release build, it can be near impossible to figure out which check as well as the source code that caused the crash. Without that information a reproducer is very hard to create.
This is a more generalised version of D118520 which has a nicer integration and should be useful to clients other than clang-tidy.
