0d9a2807 - Use UIA in MS Word by default on MS Word version 16.0.15000 or higher (#13437)

Use UIA in MS Word by default on MS Word version 16.0.15000 or higher (#13437) Microsoft Word 2016 exposes a rich UI Automation implementation. For some time now, users have been able to optionally turn this on with an advanced setting. NVDA's support for MS Word via UIA has major performance advantages over the older object model support, so NVDA should use the UIA support by default where available. However, as the UIA implementation improved throughout Office 2016's lifetime, we should only enable our support for recent builds of Office 2016, specifically for build 15000 and higher, and when only on Windows 11. This was previously tried in pr #12770 but reverted in pr #12989 The main argument for reverting was the lack of math support, and ability to report line column and section numbers. These have all been since addressed. Description of how this pull request fixes the issue: NVDA now uses UI Automation to access Microsoft Word document controls by default when on Windows 11, for Microsoft Word version 16.0.15000 and higher. The Use UI Automation to access Microsoft Word document controls when available checkbox has been replaced with a combo box with the following values: • Default (where suitable) • Only where necessary: where the Microsoft Word object model is not available at all • Where suitable: Windows 11 / Microsoft Word version 16.0.15000 or higher, or where the Microsoft Word object model is unavailable • Always: where ever UI automation is available in Microsoft word (no matter how complete). If the older checkbox was previously checked, the setting will be set to Always.
