[google_maps_android_flutter] Convert Config.sdk to minSdk in Rob…

…olectric tests and lower to `LOLLIPOP` (#7805)

Tests in the title package that are run using the Robolectric test
runner will now run on all SDKs level >= LOLLIPOP (i.e. 21). Raises max
heap size to 1G.

Affects only tests, should be version-bump exempt.

Fixes flutter/flutter#152931
