MDL-78597 mod_lti: add full field support to tool_types generator

This method is used by behat only, where only a single arg is received.
The method lti_add_type() expects two params: type and config, but will
only ever receive one. This means not all the fields can be set when
creating an lti type. This change:
- Removes the superfluous param which the method won't receive
- Improves the logic for handling type and type config data, making it
match what happens when creating types via mforms.
- Adds relative URL support to the baseurl field, allowing behat
features to create types using local tool fixtures.
- Sets sensible default for missing config data, allowing the created
tool type to be used in launches in places like behat.
