AK: Port LexicalPath to Windows

Browse source 
Supported:
* Normal absolute and relative paths: C:\Windows\Fonts, AK\LexicalPath.h
* Forward slashes and multiple separators: C:/Windows///\\\notepad.exe

Not supported:
* Paths starting with two backslashes: \\?\C:\Windows, \\server\share
* Unusual relative paths like C:, C:a\b, \, \a\b
