fix: fix issues.

- add chars format argument for floating point overload of ParserHelper::TryParse.
- add overload for ParserHelper::Parse to match with ParserHelper::TryParse.
- fix the issue that we can not specify c++ standard in command line when configuring project.
- update documentation for changes.
- change following function's argument from const yycc_char8_t* to const yycc_u8string_view&.
	- StringHelper::Split, StringHelper::SplitView
	- StringHelper::Lower, StringHelper::Upper
	- StringHelper::Join
	- StringHelper::Replace
- use iterator type, not std::vector<yycc_u8string> for specialized StringHelper::Join to have more wide usage.
