[google_maps_flutter] Switch Android examples to TLHC (#7282)

The Android example apps were still using HC mode, from when that was
the recommended option due to lost updates with TLHC. Now that the
README strongly recommends using TLHC rather than HC, we should reflect
that in our examples.

This is both a user-facing change, since it's what shows on pub.dev and
we want to set the right example there, and also changes our test
coverage. Ideally we would test both, and an issue will be filed to
explore that, but for as long as we are only testing one it should be
the recommended option.

This came up in the context of investigating
flutter/flutter#152691 where impeller on
google maps when using hybrid composition caused a crash, and I think
it's just an oversight that we hadn't changed this.
