Support moving cross-site collection with spo folder copy

This issue is related to:

• Support copying cross-site collection with spo file copy #6152
• Support moving cross-site collection with spo file move #6153
• Support moving cross-site collection with spo folder move #6154

However, spo folder copy uses the same endpoint that causes problems with the commands mentioned above, for some reason, there are no limitations for the copying of folders. However, I think it's good to keep these 4 commands aligned and let them use the same endpoint so they behave the same. Additionally, with the current endpoint, it is impossible to know the name of the new copied folder when using --nameConflictBehavior rename. With the new endpoint, this is possible.

Will work on it when #6390 has been merged. All changes made in the spo util are needed for this issue as well.
