Performance optimization for isSymbolicLink() calls on Windows

Current implementation for WindowsFileSystem.isSymbolicLink() makes unnecessary system calls which significantly affect the performance. Original code goes through the following:
- AbstractFileSystemWithCustomStat.isSymbolicLink
  - WindowsFileSystem.stat
    - WindowsFileSystem.getIoFile
    - JavaIoFileSystem.getNioPath
    - Files.readAttributes
    - WindowsFileSystem.fileIsSymbolicLink
    - WindowsFileOperations.getLastChangeTime
This implementation skips most of them.

Closes #24047.
