Add the possibility to translate CooperativeGesturesHandler on the fly

[wimpie3]

User Story

As a programmer, I'd like to specify translations on the fly for the CooperativeGesturesHandler (and possibly many other locale options too).

Rationale

Currently the locale option can be specified when constructing the map, but the localized texts cannot be changed on the fly afterwards with javascript. There is no API to do so.

Impact

When this isn't added, maps will never be translatable on the fly.

This is a large effort to do for a library without a state management system, feel free try and tackle this...

Well, unfortunately this worked without any issues in 3.6.2, with map.setCooperativeGestures...

This is because it wasn't using the right infrastructure...
The large effort I meant was to add this capability to the entire locale infrastructure.
For cooperative gesture there might be a simpler solution, you'll need to check...
