Allow compiling microsoft-ui-uiAutomation with VS 2022 (#14326)
Taken from pr #14313 which cannot yet be merged in its entirety.
Summary of the issue:
NVDA can be compiled locally with VS 2022, but the VS 2019 build tools are still required, due to the Microsoft-UI-UIAutomation project specifying the VS 2019 platform toolset by default.
Description of user facing changes
None
Description of developer facing changes
NVDA can now be fully compiled locally with Visual Studio 2022, without also requiring the 2019 build tools.
Description of development approach
• When compiling the microsoft-ui-uiAutomation project, instruct msbuild to use the same platform toolset as the rest of NVDAHelper.
