RFR: 8355697: Create windows devkit on wsl and msys2 [v2]

[kuaiwei]

> The patch fix error when creating devkit on wsl/msys2 .
> * Msys2 can be supported like cygwin
> * In wsl, it can not test path name in windows format, like `if [ -d "d:/VisualStuio"]` . The path must be converted as linux style before testing.
> * In msys2, `cmd.exe /c` doesn't work because "/c" is converted as "c:", it can be work around with `cmd.exe //c`. see https://superuser.com/questions/526736/how-to-run-internal-cmd-command-from-the-msys-shell
> 
> I tested it with win10 + wsl/msys2 + VisualStudio 2022(17.13.6)
