Add crash keys + trace when crashing due to non-main-frame OldPageInfo Currently we only set OldPageInfo for cross-BrowsingInstance same-site same-process navigations, which can only happen on main frames. However, we saw some crash reports saying that it's set for non-main frames as well. This CL adds crash keys and collects a trace when the crash happens.

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.
