Add parse depth limit to FormCalc parser
Due to the recursive nature of the FormCalc parser, deeply nested
expressions can lead to memory being exhausted. This check is being
added to have the parser exit early instead of running out of
memory. This should reduce the number of false positives about
addressing issues being found by fuzzers.
