Add Patch Task Instance Summary

[pierrejeambrun]

related to: #48584

Update the patch_task_instance_dry_run and patch_task_instance endpoints to handle ti summaries(i.e mapped TI without specifying the map_index => all of them will be affected). Default value is changed toNonebut it will not break because it supersede the-1` for unmapped tasks.

Following discussion with Brent, we should probably also support task group there.

When we will want to incorporate task groups we will encounter the same problem, we will not be able to update the patch_task_instance_endpoint.

I feel like maybe we update it (change the return type) as a bugfix because we will not be able to handle summary and task_group otherwise.

Note to self: task_group_dict get_task_group_children

I'm ok with calling the change a bug fix. We supported this in the old UI but it fell through the cracks in 3.0.0

#50550 PR for the endpoint spec fix. That can be targeted for 3.0.2. I'll update this PR to use that then, and target 3.1.0 for the ability to clear mapped task instances as a whole. (all mapped index)

Do not merge, need to be updated once #50550 is merged

I need to update the PR description before merging
