Add launch condition column

[wild-endeavor]

Why are the changes needed?

This relies on the changes to IDL in: https://github.com/flyteorg/flyte/pull/4903/files

What changes were proposed in this pull request?

• Remove bindings when embeding as query, only one binding is allowed now.
• Introduce a launch plan trigger base protocol, and add the schedule implementation of it (backend code is not ready yet so it'll throw an error for now).
• Replace poorly named additional_metadata with trigger.
• Removing some underscores in schedule model.
• Update translator to call to flyte idl on the implementation of the launch plan trigger base, with the python launch plan object itself as an arg.

How was this patch tested?

End-to-end testing with private backend will be run.
