    Reland "Vulkan: Implement EGL_EXT_device_drm[_render_node]"

This is a reland of commit 8900cbf96a3127880b1667d2242dc13a98cfe029

Original change's description:
> Vulkan: Implement EGL_EXT_device_drm[_render_node]
>
> These extensions are needed by Exo for zwp_linux_dmabuf v4 support.
>
> Unfortunately `VkPhysicalDeviceDrmPropertiesEXT` doesn't give us the
> information about the filesystem layout, needed by the EGL version.
> As ChromeOS is currently the only user, implement the extension only for
> Linux where we can reasonably assume `/dev/dri/...` file paths.
>
> We do not, however, limit us to the GBM backend - having the extension
> working in e.g. a nested X11 or Wayland environment is quite helpful.

  • ANGLE - Almost Native Graphics Layer Engine

    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, 3.0 and 3.1 to Vulkan, desktop OpenGL, OpenGL ES, Direct3D 9, and Direct3D 11. Future plans include ES 3.2, translation to Metal and MacOS, Chrome OS, and Fuchsia support.

    ANGLE v1.0.772 was certified compliant by passing the OpenGL ES 2.0.3 conformance tests in October 2011.

    ANGLE has received the following certifications with the Vulkan backend:

    • OpenGL ES 2.0: ANGLE 2.1.0.d46e2fb1e341 (Nov, 2019)
    • OpenGL ES 3.0: ANGLE 2.1.0.f18ff947360d (Feb, 2020)
    • OpenGL ES 3.1: ANGLE 2.1.0.f5dace0f1e57 (Jul, 2020)

    ANGLE also provides an implementation of the EGL 1.5 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, Vulkan GLSL, Direct3D HLSL, and even ESSL for native GLES2 platforms.
