RFR: 8349006: File.getCanonicalPath should remove "(on UNIX platforms)" from its specification [v3]

[Brian Burkhalter]

> The change made for [JDK-8003887](https://bugs.openjdk.org/browse/JDK-8003887) updated `File.getCanonicalPath` to resolve symbolic links on Windows, but its specification was not modified to reflect this. Here it is proposed to correct that omission.
