> While adding JSON_TYPE, we mapped some improvements that can be also used by
> JSON_LENGTH:
> # isPathDefinite is a function that can be added to the codegen stage to
> make json_length more optimal, that way isPathDefinite only runs once.
> # Add the strict/lax validation check to codegen stage to make json_length
> more optimal, that way the json_path is only ever parsed against the regex
> once, also change regex to "\\s*(strict|lax)\\s+\\$.*".
> # reuse getOrCreateParsedJson(jsonType) for jsonLength.
