## Description
Pick what data to source from a base snapshot by examining the reason the snapshot was selected as a base. This helps avoid two issues:
* pulling in unwanted data when the base has a superset of what is being backed up. Example: pulling in contacts from the base when only email is being backed up
* clobbering already selected data from a different base with data in the base currently being examined. Example: two snapshots, one with contacts and emails and the other with just emails. Second snapshot is newer than the first. The email items in the first snapshot should not clobber those in the first when building the hierarchy
This PR also has the effect of, under some conditions, reducing the amount of data that is pulled from the remote kopia repo when building the hierarchy. This occurs because only the subtrees that will be used in the new backup are traversed instead of traversing the entire snapshot

## Description
Merge directory layouts between the passed in collections and the base snapshot(s). Also add unit tests to ensure the output kopia hierarchy looks as expected. (CLI) user observable behavior is not affected by this PR
This PR does not address:
* selecting subtrees for specific data categories in base snapshots
* not clobbering more recent info if multiple snapshots have subtrees for the same data category (ties into above)
* file deletions for services that can only report item deletions at a global level (e.x. OneDrive file deletions)

## Description
Adds a flag in backup details that indicates whether the item in that backup is new/updated.
Currently always set to `true` but once we implement #1800 - we will set this to false for existing items from
base snapshots.

## Description
Create and wire up a helper function that merges items in the base snapshot with items that have been seen from the collection
Will not change the output of execution at all since the base snapshot directory will always be nil at the moment
Will require further modifications to properly handle deleted items where only a single delta endpoint is used to fetch changes (e.x. OneDrive file deletions)

## Description
Instead of relying on KopiaWrapper to create the OwnersCats for a
backup, have BackupOp create them from the selector and pass them in.
This is necessary as incremental backups will no longer see all the data
in the backup, meaning it cannot accurately create the OwnersCats
because some data categories or owners in the backup may not have had
changes.
OwnersCats are eventually converted to tags on a kopia snapshot and used
to lookup snapshots when trying to find base snapshots for incrementals.
Additional minor changes:
* use pointers instead of values when passing parameters
* set backup details OwnersCats to nil

Instead of rolling our own logic for injecting a version, use a
MultiReader to concatenate the streams. Handling Close() is now more
complex though.

Pull code specific to making snapshots in kopia into a separate file. Factor out code specific to handling collections in preparation for having to deal with kopia items as well during incremental backups. Apart from code movement and factoring into functions no other changes have been made
