[google_maps_flutter_web] Options to disable tilt controls and configure gesture handling

[Rexios80]

Use case

On web, Google Maps has tilt controls that show up sometimes, these should be toggle-able.

On web, Google Maps will sometimes show an overlay that you must use two fingers or cmd+drag to move the map. The gesture handling options let you change this behavior. Specifically the greedy option makes this overlay go away and lets the user drag the map as usual.

Proposal

Update the google_maps_flutter_web plugin to expose these features
