Auto merge of #21583 - AgustinCB:add-task-source-name, r=jdm

Add task source name

Refactor `CommonScriptMsg::Task` to include `TaskSourceName`.

Sorry for the delay, between doing this after work and the time I spent trying to ramp up on the project, it took me a bit longer than I expected.

Test still don't pass in local, but they fail the same way on master, so I guess it's ok.

I may have forgotten something, I refactored mostly the stuff that the compiler complained about. Please let me know if I missed anything.

I tried to dump my thought process on the commit messages, so feel free to go commit by commit to understand context.
