[maps embeddable] fix map layers disappear from map panel when using session storage to continue editing a dashboard

[nreese]

Closes https://github.com/elastic/kibana/issues/190468 and https://github.com/elastic/kibana/issues/193601

Dashboard unsaved changes for a panel are obtained from the embeddable comparator subject for each comparator. If comparator subject does not return a value, then this information is lost when returning to a dashboard with unsaved changes. This is why layers and filters where disappearing from a map when returning to a dashboard with unsaved changes. This PR resolves this issue by providing comparator subjects and setters for savedObjectId, attributes, and mapSettings.

PR also resolves issue of passing props from MapRenderer component into map embeddable. Instead of passing props via state, props should be passed from MapRenderer parent api.
