[A11yPerformance] Rename AXMode::kScreenReader to kExtendedProperties

The new name is much more descriptive of what the mode actually is,
since many non-screen readers can also turn this mode on.
In addition, having it be called screen reader mode is confusing
since we do now have actual screen reader detection.

In fact, working on this makes it clear there are current features that
actually think they're switching behavior based on the presence
of a screen reader, but are really getting a signal if a utility
or OS feature was using a11y APIs. The percentage of users with
the misnamed kScreenReader mode was over 10% on some platforms!
Bug 401443089 has been filed to audit all the call sites that
used AXMode::kScreenReader and use actual screen reader detection
(see CL:6336045 for an example of how to do that).

This is a foundational piece for separating out two different concepts
in BrowserAccessibility related to whether a screen reader is present,
so that we can carefully use the right signal for turning off
ProgressiveAccessibility/AutoDisable when a screen reader is present.
The current kScreenReader mode is a misnomer.
