feat(cli): allow CompositePlans to be created based on activities

[Panaetius]

closes #2323

Other than what the linked issue mentions, @rokroskar suggested that we keep rerun as is, supporting reproducibility.

If a user wants to rerun a pipeline with modified parameters, they can now use renku workflow compose --from <input> --to <output> to create a CompositePlan encompassing all the plans that a rerun would execute, with proper values applied (using mappings on the composite). This plan can then be executed using renku workflow execute with modified parameters.

Example Usage:

$ renku run --name run1 -- echo "hello" > output1
$ renku run --name run2 -- cp output1 output2
$ renku workflow compose --to output2 my-composed-workflow
$ renku workflow execute --set 1-parameter-1="Hello World" my-composed-workflow

Note, some refactorings in this PR are the same as in #2372 (namely the sort_activities and get_activities_until_paths ones)
