Support suggested name and icon for dashboards, add to map

Breaking change

Proposed change

Adds support for dashboards to suggest creation details. Currently name and icon are supported. URL is generated as if typed in if title is set.

A dashboard can suggest its own data by adding this function:

  static getCreateSuggestions(
    hass: HomeAssistant
  ): LovelaceDashboardSuggestions {
    return {
      title: hass.localize("panel.map"),
      icon: "mdi:map",
    };
  }

This has been added for the map dashboard.

Also works for custom dashboards.

Also added a helper function to check available paths from the existing set, appends -2, -3 incrementally until one is available. Makes a little more user friendly, when adding multiple of the same dashboard (or one of the same title suggestion)
