Switch inline switcher and multiple action schema to use dynamic action schema creation API

[curtisman]

Inline switcher and multiple action schema to use dynamic action schema creation API, whether we use the in-memory validator or type script validate.

Also, leveraging the above implemented a function to generate composite schema that is sent to the LLM (that includes the injected, inline switcher and multiple action) and wired that to agent-cli schema --generated. It is not used in the actual action translation yet, and will be in a follow up PR.

Additional change:

• Add capability to have type reference that is not resolved (for the multiple action case), with the assumption that the definition will be somewhere.
  • During generation, it will error out by default if there are unresolved type reference, but will ignore if { strict: false} is passed in to the generation function.
• Add template parameter for SchemaType types so that it can narrow the type of fields, etc. Use to specify the shape of an ActionSchema, and has the compiler/intelligence know of the fields (actionName and parameters)
• Starting to transition the translator nomenclature to refer to a set of action schema for an app agent, and switch to action or actionSchema
• Change the natural order of schema generation to be "depth" first so that type references are close to each other.
