Move focus from location bar to view

This MR conains two commits about moving the keyboard focus from the location bar to the view:

Have "Replace Location" toggle focus of the view

The "Replace Location" action moves focus to the location bar and
selects the full path there so it can easily be replaced with a
different path.

When the full path is already selected, triggering "Replace
Location" will toggle the editable state of the location bar.
This commit makes it, that this also moves the focus to the view.
This way, pressing Ctrl+L multiple times will switch back and forth
between focusing and selecting the location bar path and focusing
the view. This seems more sensible than only partially resetting
the state when the "Replace Location" keyboard shortcut is pressed
twice.

Make Escape move focus from location bar to view

Pressing Escape on the location bar while in breadcrumb mode has no
effect at all. This commit changes this to instead move the focus
to the active view. This is more logical because a user pressing
escape while having focus on the location bar is no longer
interested in interacting and changing the location in the location
bar. They most likely want to act on the current location instead.

Aside from improving the user experience, these are also improvements for accessibility, because especially for blind users jumping quickly to the location bar to get the current path read out is useful, but then also requires ways to quickly jump back to the view.
