Refactoring of LLFile class to support additional methods

- LLFile with its own class method interface to access files for read and write
- Remove rudimentary LLUniqueFile class as LLFile supports now all of that and more
- Implement most of the filename based functions using std::filesystem functions
- Replace LLFile::rmdir() with LLFile::remove() since this function now supports deleting files and directories on all platforms.
