 Follow symlinks in the Win32 code for System.Environment.getExecutablePath

 This partially addresses #14483 by fixing the Windows implementation of
 System.Environment.getExecutablePath. This is achieved by using
 GetFinalPathNameByHandleW to resolve potential symlinks, while making
 sure we do not get back a UNC path (see #14460).

 Test Plan: Validate
