Improve File.symlink for Windows

[nof1000]

That's implements symlink on Windows. But please note that we cannot make symlink on Windows without Administrator privileges. It might be is worth writing about this in the documentation

Could you add such a note to File.symlink?

Also needs a rebase.

This is Wrong.
Starting with Windows 10 v14972 and upwards, one can enable symlinks without admin privileges when Developer Mode is enabled. (settings > updates and security > for developers > toggle the developer mode on).

@mominshaikhdevs Thanks for clarification. This is actually mentioned in the code comment, btw.

[mominshaikhdevs]

should this PR be closed since #13141 is merged ?
