[Backport] 8333462: Performance regression of new DecimalFormat() when compare to jdk11

Summary: The DecimalFormat constructor calls DecimalFormatSymbols.findNonFormatChar(String,char) multiple times, and the lambda implementation is slow than plain loop implementation of DecimalFormatSymbols.findNonFormatChar(String,char).

Testing: All java.text.format jtreg.
