[google_maps_flutter] Annotate deprecated member usage (flutter#8214)

There are several intentional uses of deprecated members from other packages within the plugin group, so annotate them so that they don't show up in the regular team audits:
- App-facing package integration tests of the deprecated style method.
- Handling of deprecated marker bitmap formats.

These turned up in the [routine repo audit](https://github.com/flutter/flutter/blob/main/docs/infra/Packages-Gardener-Rotation.md#deprecations).
