  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.
