Feature: Use the registered copy handler for copy/move operations

[ilbalta]

What's the Problem?

Currently Files handles move/copy operations "internally", this is slower than explorer.exe (documented here) and does not support third party programs handling move/copy operations (e.g., TeraCopy).

Solution/Idea

It would be interesting to, instead, have the possibility to use the registered copy handler to allow a smooth integration of third party programs such as TeraCopy. This could also possibly make Files as fast as the default explorer as, it is my understanding, the registered copy handler by default is explorer.exe itself.

Alternatives

Currently I use the contextual menu for TeraCopy, this is clearly sub-optimal as it requires several more clicks for all move/copy operations (not only the right click but the TeraCopy contextual menu is hidden under the "... More >" entry)

Priorities

| Capability | Priority |
| Support other Copy Handlers | Must |
| Support the usage of the default registered Copy Handler | Should |

Just curious: Do you experience other advantages in using TeraCopy over the default Files copy operations besides increased speed?

[ilbalta]

If I have to perform several big move operations with TeraCopy I can easily schedule them (e.g., move game A from SSD to HDD, then move game B from HDD to SSD).
Also it checks for the operation to be successful, maybe it's placebo but it makes me feel safe :D

+1 for Teracopy integration !

Asking @yaichenbaum for approval.

I'm not familiar with this to know if we can integrate with them. Deferring to @gave92

I'm not familiar with this either. I know Teracopy registers itself as a drag&drop handler. Explorer++ code is a good place to see how to invoke it.

@ilbalta I presume that this will be possible when we migrate to WinUI 3 so I'll approve this but we're going to need some help on this.
