Web Inspector: make ObjC protocol dispatcher commands optional and add `respondsToSelector` checks to allow other inspector clients to choose what they implement
https://bugs.webkit.org/show_bug.cgi?id=203197

Reviewed by Joseph Pecoraro.

This will help eliminate internal build failures, and will also allow other clients to
remove all of their commands that previously just responded with an "unsupported" error.

* inspector/scripts/codegen/objc_generator_templates.py:
* inspector/scripts/codegen/generate_objc_backend_dispatcher_implementation.py:
(ObjCBackendDispatcherImplementationGenerator._generate_handler_implementation_for_command):
(ObjCBackendDispatcherImplementationGenerator._generate_responds_to_selector_for_command): Added.
Add a `respondsToSelector` check before attempting to call the delegate function.

* inspector/scripts/codegen/generate_objc_header.py:
(ObjCHeaderGenerator._generate_command_protocols):
Mark all commands as `@optional`.
