Add support for Windows UI Automation

Replaces the Qt Accessibility Windows back end, formerly based on legacy
MSAA, with a new implementation based on UI Automation. Fixes issues with
accessibility tools like screen readers and magnifiers, and with the
automatic showing and hiding of the virtual keyboard in touchscreen-based
Windows computers.

[ChangeLog][Windows] The Windows Accessibility back end, formerly based on
Microsoft Active Accessibility, was replaced with a new implementation
based on Microsoft UI Automation.
