…nfiguration (#43878) (#44044)

* [Maps] Provide ability to create MapEmbeddable directly from a map configuration

* call updateInput instead of passing modified input to MapEmbeddable constructor

* cleanup i18n translations

* update map embeddable documenation to reflect createFromState examples

+### Map specific `input` parameters
+- **hideFilterActions:** (Boolean) Set to true to hide all filtering controls.
+- **isLayerTOCOpen:** (Boolean) Set to false to render map with legend in collapsed state.
+- **openTOCDetails:** (Array of Strings) Array of layer ids. Add layer id to show layer details on initial render.
+- **mapCenter:** ({lat, lon, zoom }) Provide mapCenter to customize initial map location.
