ARROW-15674: [C++][Gandiva] Like function doesn't properly handle patterns with special characters in certain cases

For example following pattern 'abc-xyz%' doesn't work however 'abc-xyz' works. This is because special characters are escaped to work with regex matcher, but when they are optimised with starts_with/ends_with/is_substr function these escape characters are not currently removed for the default case ('\\' escape char).

Closes #12417 from projjal/fixlike
