feat(google-maps): MapsAdvancedMarker should support gmp-click and gmp-clickable

[jermowery]

Feature Description

This is the feature by which advanced marker elements can be made to be interactive and accessible: https://developers.google.com/maps/documentation/javascript/advanced-markers/accessible-markers

This is missing in Angular

Use Case

• Fixing an accessibility bug in my own internal Google project
• Improve maps accessibility for Angular generally

I will send a quick PR to fix this
