  [BOLT][NFC] Add BOLTError and return it from passes (1/2) (#81522)

As part of the effort to refactor old error handling code that
would directly call exit(1), in this patch we add a new class
BOLTError and auxiliary functions `createFatalBOLTError()` and
`createNonFatalBOLTError()` that allow BOLT code to bubble up the
problem to the caller by using the Error class as a return
type (or Expected). Also changes passes to use these.
