[google_maps_flutter] Undeprecate BitmapDescriptor methods (#6832)

Undeprecate BitmapDescriptor.fromAssetImage and BitmapDescriptor.fromBytes

* Undeprecates `BitmapDescriptor.fromAssetImage`.
* Undeprecates `BitmapDescriptor.fromBytes`.
* Fixes issues with deprecation in version 2.7.0.

The new formats won't be supported until #6826 lands.
Deprecation notices can be re-added after the implementation PRs have landed.

Fixes: flutter/flutter#149183
