refactor: update project

- add documentation CMake build script. re-organise document layout for future changes.
- move LIBCMO_EXPORT to BMap and rename it to BMAP_EXPORT because only BMap need to use this macro.
- fully refactor VTEncoding to make it more like Python
	- Now language name is platform independent.
	- Hide implementation detail as possible as I can.
	- Language mapping are still work in progress.
- add code gen for new added universal encoding feature to generate language name mapping in Windows and Iconv respectively.
- remove old code of CMake build script.
- update VTUtils for new requirement.
	- remove useless functions.
	- create LibCmo specific custom exception classes.
