[formrecognizer] Consistency issues

[catalinaperalta]

Look into:

• checkout model naming in begin_analyze_document do we use model_id everywhere else? Should we unify?
• rename begin_create_compose_model -> begin_compose_model - follow up
• rename get_account_info -> get_resource_info
• rename AccountInfo -> ResourceInfo
• check the dict[str, str] returned from get_copy_authorization...other langs use a model should we have a typed dict?
• rename documentmodelinfo to documentmodelsummary. also documentmodel to documentmodelinfo
• GA blocker is the service going to support different input source types?
• rename target to authorization on copy model - follow up
