Vulkan: Implement Transform Feedback support via extension
Implemented transform feedback extension path. Where
VK_EXT_transform_feedback is supported, extension path will be taken
over an emulation path. Extension path has advantages in terms of
performance.
BUG=angleproject:3206
Test: dEQP-GLES3.functional.transform_feedback.*

Vulkan: Set empty buffer to xfb descriptor set as an initial buffer
When we have xfb descriptor set without buffer bindings it causes
errors in Vulkan validation layer. So we set empty buffer by default.

Vulkan: Fix crash with glBeginTransformFeedback
The TransformFeedbackVk::onBeginEnd() method wasn't calling updateQueueSerial(),
which was causing CommandGraphResource::hasChildlessWritingNode() to use an old
mCurrentWritingNode, which had already been freed (i.e. Visual Studio showed it
pointing to memory that is 0xdddddddd--which means that mCurrentWritingNode has
been freed, but is still being used).
Unfortunately, there are still other crashes affecting these tests, but they
are the same set (and yes, there are multiple, and they are random) that cause
most of the "KHR-GLES3.copy_tex_image_conversions.required.*" tests to crash).

Vulkan: Prepare for variable-stage pipelines
Compute (single-stage pipeline) is upcoming, but this change prepares
GlslangWrapper to handle any number of stages (mostly). Additionally,
this change binds each resource to each stage based on whether it's
active, so that we don't hit the per-stage limit of resources by binding
every resource to every stage.

Vulkan: Emulate Transform Feedback with vertex shader output
In ES 3.0 and 3.1, only non-indexed GL_POINTS, GL_LINES and GL_TRIANGLES
is supported for transform feedback. Without tessellation and geometry
shaders, we can calculate the exact location where each vertex transform
output should be written on the CPU, and have each vertex shader
invocation write its data separately to the appropriate location in the
buffer.
This depends on the vertexPipelineStoresAndAtomics Vulkan feature.

Proliferate gl::Context everywhere.
This gives the D3D back-end access to the GL state almost anywhere.
This uses the onDestroy hook for Textures to push errors up from
destructors, although they still don't quite make it to the Context.
There are places, such as in EGL object (Context/Surface) destruction,
where we end up calling through to GL implementation internals without
having access to a gl::Context. We handle this via a proxy Context
to a Display, basically a null context, that has access to impl-side
state like the Renderer pointer if necessary. It does not have access
to the normal GL state.
Also Pass gl::Context to RefCountObject::release(). Since we're using
destroy() methods now, we should not ever call the destructor directly.

Support virtualized contexts and transform feedback in Renderer11.
Track buffer offets in the transform feedback object and dirty them when a
buffer is bound. This fixes problems when a buffer is rebound at the same
offset and maintains tracking between context switches.
