Fix a crash with empty escape sequences when lexing (#102339)
The utilities we use for lexing string and character literals can be run
in a mode where we pass a null pointer for the diagnostics engine. This
mode is used by the format string checkers, for example. However, there
were two places that failed to account for a null diagnostic engine
pointer: `\o{}` and `\x{}`.
This patch adds a check for a null pointer and correctly handles
fallback behavior.
Fixes #102218
