    Vulkan: Use push constants for driver uniforms

* Updated the driver uniforms so they would be defined as push
  constants in SPIR-V. Their data would be updated via
  pushConstants() when handling the driver uniform dirty bits.

* Updated TOutputVulkanGLSL to be able to generate the push
  constants as required.

* When handling the driver uniform dirty bits, we no longer
  allocate a buffer.

* Removed the driver uniform descriptor set from the pipeline
  layout.

* Removed the binding-related functions and flags for the driver
  uniforms.

  * In invalidateGraphicsDescriptorSet(), DIRTY_BIT_DESCRIPTOR_SETS
  is used instead of DIRTY_BIT_DRIVER_UNIFORMS_BINDING. (Same for
  invalidateComputeDescriptorSet())

  * DIRTY_BIT_DRIVER_UNIFORMS_BINDING is replaced with
  DIRTY_BIT_DRIVER_UNIFORMS in other places.

* Removed mDriverUniform and DriverUniformsDescriptorSet from
  ContextVk.

* Added mSupportedVulkanShaderStageMask to RendererVk, which is used
  in creating the pipeline layout and updating the push constants.

* Added a TODO note for driverUniformsDescriptorSetIndex.

  • 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.
