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.

The goal of ANGLE is to allow users of multiple operating systems to seamlessly run WebGL and other OpenGL ES content by translating OpenGL ES API calls to one of the hardware-supported APIs available for that platform. ANGLE currently provides translation from OpenGL ES 2.0 and 3.0 to desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Support for translation from OpenGL ES to Vulkan is underway, and future plans include compute shader support (ES 3.1) and MacOS support.

ANGLE v1.0.772 was certified compliant by passing the ES 2.0.3 conformance tests in October 2011. ANGLE also provides an implementation of the EGL 1.4 specification.
ANGLE is used as the default WebGL backend for both Google Chrome and Mozilla Firefox on Windows platforms. Chrome uses ANGLE for all graphics rendering on Windows, including the accelerated Canvas2D implementation and the Native Client sandbox environment.
Portions of the ANGLE shader compiler are used as a shader validator and translator by WebGL implementations across multiple platforms. It is used on Mac OS X, Linux, and in mobile variants of the browsers. Having one shader validator helps to ensure that a consistent set of GLSL ES shaders are accepted across browsers and platforms. The shader translator can be used to translate shaders to other shading languages, and to optionally apply shader modifications to work around bugs or quirks in the native graphics drivers. The translator targets Desktop GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
