[CodeHealth] Remove TransferUserActivationFrom function from browser and renderer

Since we will not use this experimental feature to transfer user
activation through post message to autoplay videos in a cross-origin
subframe without any user activation. We will delete the
TransferUserActivationFrom function from browser and renderer, which is
called from post message to transfer user activation from one frame to
the other frame.

We will also clean up the frame interfaces in browser/renderer in a
follow-up CLs.

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.
