[Maps][Telemetry] Migrate Maps telemetry to NP (elastic#55055)

* Move maps telemetry to NP. Some clean-up, some ts conversion

* Update naming & org to be more in-line with guidelines

* Get TELEMETRY_TYPE from constants

* Ignore ts error importing from js file

* Set original array type passed into the function to array of ILayerTypeCount. Set return type on reduce function

* Remove unneeded 'any' types where used. Add in interfaces for map & index pattern saved objects

* Review feedback. Add layer, source, map saved object types and use

* Review feedback. Updates based on type check
