Add missing SWT for Windows on Arm64 (WoA) fragment to the compare win32 plug-in.

Because of the discussion in eclipse-platform/eclipse.platform.releng.aggregator#577 (comment), can you please split this into multiple PRs, one for the addition of a org.eclipse.core.filesystem.win32.aarch64 and one for a org.eclipse.core.resources.win32.aarch64 so that we can discuss them separately?

The change of org.eclipse.compare.win32/META-INF/p2.inf can be applied now, so having that in a third PR would allow us to land it immediately.

Yeah, I'm re-making this PR to be the third one of the three PRs.

Looks good, thank you.
But when reading through Bug 361901 I wonder if that p2.inf file is even necessary at all?
The SWT host bundle already has something like that so I actually wouldn't expect that to be necessary again?
@merks can you tell better?

Nevertheless I'll submit this now and we can still remove the entire file later if we conclude that it's obsolete.

I imagine each separate host bundle can benefit from filtered requirements on the known fragments. Without this, one must rely on some feature encoding those requirements or replicating them somewhere downstream.
