Remove embedded_android_views (on-device) tests, same as emulator test (flutter#173814)

These tests are identical to the `Linux_android_emu` test that runs on
presubmit:


https://github.com/flutter/flutter/blob/9583f282a50f88a269f5716f1ecfe42f6b6387a3/.ci.yaml#L408-L416

These tests do not report benchmarks or any other statistics that would
benefit from a real (on-device) test.
