Support full regular expression on PatterMatcher.match()

[injae-kim]

related issue #4412

Motivation:

• On Add support for full regular expressions in PatternMatchingCompositeLineMapper #4412, we found that PatternMatchingCompositeLineMapper doesn't support regular expression matching
  • It only supports AntPathMatcher style matching now

Modification:

• Support full regular expression on PatterMatcher.match() that used on PatternMatchingCompositeLineMapper.mapLine()

Result:

• Now user can use full regular expression matching on PatternMatchingCompositeLineMapper.mapLine()
• Close Add support for full regular expressions in PatternMatchingCompositeLineMapper #4412 issue

Maybe we can replace match() to matchRegex(), but I think it makes breaking change.

• e.g. "*" means matching all lines on match(), but invalid regex format and throws PatternSyntaxException on matchRegex()
• "abcde" matches "abc*" on match(), but not matches on matchRegex() ("abc*" matches only "abccc.." on regex)

(also PatternMatcherTests failed if we replace match() to matchRegex())

To avoid this breaking change, I intentionally matchRegex() only when there's nothing matched by match()~!
