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.
