Alan Donovan a45bbeae33 go/token: add (*FileSet).RemoveFile(*File) method
The design of FileSet encourages it to be used as a global variable.
Each call to AddFile consumes about 3KB, that is never returned,
even after an application no longer cares about the File.
This change adds a RemoveFile method that a long-running application
can use to release a File that is no longer needed, saving memory.

Fixes golang/go#53200
