    Message : Add support for generating UWP (Windows Store) projects again Until late 2017, ANGLE supported Windows Store apps on Windows 8.1, Windows Phone 8.1, and Windows 10 (via the Universal Windows Platform, aka UWP). Unfortunately ANGLE deprecated support for Windows Store when it switched from GYP to GN in 2017. Since then, users have been able to use Microsoft\angle for their UWP apps but this isn't ideal since it's based on a 2017 copy of Google\angle. This PR bring back support for UWPs, so that UWP users can use Google\angle again. Specifically it: - Adds support for generating UWP projects via GN - Adds helper/util functions specific to UWP (they're mostly similar to the desktop Windows helpers) - Fixes some existing Windows Store code that's rotted since 2017 - Disables async shader compilation for UWPs, since its implementation calls wait on the UI thread (which is forbidden in UWPs) - Renames 'ANGLE_ENABLE_WINDOWS_STORE' to 'ANGLE_ENABLE_WINDOWS_UWP', since ANGLE only support UWPs now - Fixes misc other related issues (such as dependencies on D3D9 headers in API-agnostic code) Note that this doesn't bring back support for Windows/Phone 8.1.
