feat: Feature state

[davor-bauk-sh]

Description

Adds support for setting, getting, and removing feature state (issue #1807).

await this._map.setFeatureState('my-feature-id', { 'my-state-key': true }, 'my-source-id', 'my-source-layer-id');

await this._map.getFeatureState('my-feature-id', 'my-source-id', 'my-source-layer-id');

await this._map.removeFeatureState('my-feature-id', 'my-state-key', 'my-source-id', 'my-source-layer-id');

Notes

I had trouble building the Android example project, which I solved by adding this to /example/android/settings.gradle:

includeBuild('../android')

@mfazekas Is there a reason why this feature is not moved forward? It would be quite convenient in many different cases. Thank you :)

@davor-bauk-sh thanks much for looking into it, amazing work! Looks great for the first glance will be looking into it in details later this week. Sorry for the long turnaround

[mfazekas]

@davor-bauk-sh there are some android ci failures, you might need to rebase to/merge current main

[davor-bauk-sh]

@mfazekas Rebased my branch on main. Hopefully CI will pass, otherwise I might need some help looking into the CI failures.

@davor-bauk-sh for some reason I wasn't able to get this working on this branch. I've needed to add v11 callback support, but otherwise it was working nice. It's merged now, thanks again!
