Currently, if a user runs `regexp_like(c2, '[abc-d-12]')`, they receive a cryptic error message like "Illegal character range near index ..." and this is unclear when the sql is quite complex. Move the `RegexpExtractExprMacro.compilePattern()` utility into a shared location and have all Regexp* macros use it, so that invalid regex patterns produce nicer error messages for users. #### Release note Nicer user-facing error messages for invalid patterns used in the regexp* functions. <hr> <!-- Check the items by putting "x" in the brackets for the done things.
