Reland "[WebLayer] Change the return type of Fragment.getActivity() to Activity."

This is a reland of ae52b2a4a4f3fdf121619fc62f300883b610bd46 with fixes
for robolectric tests, which run on the JVM which appears to have
stricter verification checks.

Original change's description:
> [WebLayer] Change the return type of Fragment.getActivity() to Activity.
>
> This CL adds the ability to specify a script in an android_aar_prebuilt
> rule that can modify prebuilt jar files, and adds a script to change
> Fragment.getActivity() and Fragment.requireActivity() to return an
> Activity instead of a FragmentActivity.
>
> This is the first CL in a chain that will allow us to remove the fake
> activity we create when embedding Fragments that cross classloader
> boundaries.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
