Rename to_different_document to should_show_loading_ui in LoadingStateChanged() callbacks

Currently, the purpose of this bit is to indicate to embedders whether
or not a navigation should show loading UI indicators. Currently, same
document navigations never show loading UI because they're always
processed synchronously, so there's no point in flipping to showing
loading UI only to immediately turn it off again. However, in a future
patch, we will introduce a new asynchronous kind of same-document
navigation (as part of the new appHistory API). In preparation for
that, rename to_different_document to should_show_loading_ui to better
indicate what the bit means and how it should be used.

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.
