Handle RWHV scale override for Android

This CL makes RWHVA handle scale override. Scale override is used
during tab casting, and it modifies ScreenInfo. RWHVB takes this
into account by using GetDeviceScaleFactor, but the current code
does not handle this.

In the case that there is no override scale, then
GetDeviceScaleFactor() / view_.GetDipScale() will be exactly 1.0 so
the pixel off-by-ones that https://crrev.com/c/6169396 was fixing
will still be okay.

When override scale is set the expected behaviour is to scale the
buffer down (or up) to fit the size it would normally be shown at.

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.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

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.

If you found a bug, please file it at https://crbug.com/new.
