Diagnostic comparison using parsing (#1683)

* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP diagnostics for line number output.

* Small param naming change

* Use x macro for pass through compile human name lookup/getting.

* WIP on parsing downstream compiler output.

* Split out parsing into ParseDiagnosticUtil.
Added test result of single line.

* Dump out the std output on fail to parse diagnostics.

* Change test type for syntax-error-intrinsic.slang be TEST not TEST_DIAGNOSTIC

* Use Index for StringUtil.

* WIP: First pass support for parsing Slang diagnostics.

* WIP Testing comparing with ParseDiagnosticUtil with previous ad-hoc mechanism.

* Use the new parsing mechanism for diagnostic comparisons.

* Improvements to diagnostics parsing.
Better error handling, and fallback handling.
Added ability to parse downstream compilers without a prefix.
Added ability to parse Slang with a prefix.
