Allow complex depency flow by adding resource_deps to more functions

I have multiple services set up with multiple tilt files. For testing I sometimes run tilt files one by one, but to setup the whole cluster I want to be able to run all of them through a single Tiltfile, while still respecting decency flow.

The resources and resource_deps are perfect for this, however, they are only present on functions that create resources themselves (k8s, local, dc etc.), while for my use case I imagine I would need a resource_deps on the load_dynamic function.

Is there another way to go about dynamic and staged loading with multi Tiltfiles while still allowing them to be executed separately?

If not, I would like to propose adding resource_deps to other functions, such as load_dynamic

Review the Tiltfile loading entry point and the existing resource_deps handling on k8s, local, and dc functions, then trace load_dynamic's behavior. Define whether load_dynamic should accept resource_deps or another supported mechanism while preserving standalone and aggregate multi-Tiltfile execution, and validate the chosen behavior with relevant tests.
