[jdk19] RFR: 8289486: Improve XSLT XPath operators count efficiency [v2]

[Joe Wang]

> To improve efficiency, this patch moves the limit check to within the Lexer and reports any overlimit situation as soon as it happens.
> 
> Note the change in XPathParser: diff (and also webrevs) showed the whole error-report block was changed, the actual change was only placing the block to within the isOverLimit statement.
> 
> Test: java.xml tests passed.
