Fix incorrect SubMonitor usage patterns

[vogella]

This commit addresses several SubMonitor anti-patterns identified throughout the codebase, based on best practices from the Eclipse article on Progress Monitors.

Changes made:

1. Remove unnecessary null checks before SubMonitor.convert()

   • SubMonitor.convert() can handle null monitors
   • Fixed in team Policy.java files (core and ui)

2. Remove unnecessary SubMonitor.done() calls

   • SubMonitor.done() is a no-op and should not be called
   • Removed 27 instances across resources and team bundles:
     • org.eclipse.core.filesystem: LocalFile.java (2 calls)
     • org.eclipse.core.resources: File.java (6), Folder.java (1), Project.java (3), SaveManager.java (4), Workspace.java (7) * org.eclipse.compare.core: RangeComparatorLCS.java (1) * org.eclipse.compare: AddFromHistoryAction.java (1) * org.eclipse.team.core: BundleImporterDelegate.java (1), Subscriber.java (1)

3. Remove redundant cancellation checks before split()

   • SubMonitor.split() already checks for cancellation
   • Fixed in AutoBuildJob.java
