Bump versions of agp and robolectric, and configure to use SDK 35 (flutter/engine#56732)

Bumps the version of AGP used in the IDE-support `build.gradle`, as well as the robolectric version in both the IDE-support `build.gradle` and test-runner-`build.gradle`. 

This is the current latest robolectric: https://github.com/robolectric/robolectric/releases/tag/robolectric-4.14.1.

Also 
1. configures robolectric to use API 35, and 
2. removes the use of a deprecated class which (from what I could tell) looked like it was just used for setup, and the test still passes without it.
