Allow single threaded CommandProcessor
In replacing the legacy CommandQueue code with the threading
capable CommandProcessor it would be good to be able to run the
CommandProcessor in a single-thread environment. This CL changes the
meaning of the feature flags for the commandProcessor and
asynchronousCommandProcessing so that enabling commandProcess only
changes the code paths to use the command processor but work it still
done as part of the submitting thread (e.g. ContextVk).
Enabling asynchronousCommandProcessing will cause a separate worker
thread to be spawned which will asynchronously process the commands.
This allows us to switch to the CommandProcessor without threading and
then enable threading once performance issues are resolved.

Vulkan: Fix EGL Surface robust init.
The error here was related to using a single cache variable for the
robust init setting for all the surfaces in a DisplayVk. Fix this by
passing down the robust init setting from the SurfaceVk to image init.

Vulkan: functionally complete worker thread
Working on enhancing worker thread to completely own primary command
buffers. This will include not only processing SCBs from main thread
into a primary, but also submitting those command buffers to the queue.
The CommandProcessor is a vk::Context so it can handle errors in the
worker thread. When the main thread submits tasks to the worker
thread it also syncs any outstanding errors from the worker.
Include asynchronousCommandProcessing feature that will control
whether the worker thread task does it's work in parallel or not. If
false, we wait for the thread to complete it's work before letting the
main thread continue. If true, the thread can execute in parallel with
the main thread.

Vulkan:Initial worker thread disabled by default
Created new CommandProcessor class that can be run as a worker thread.
Running CommandProcessor within RendererVk as a worker thread that
takes a CommmandBufferHelper (CBH) ptr as the interface and processes
that CBH into a primary command buffer.
Main thread has a queue of CBH to draw from. After submitting a CBH to
the worker, it pulls next CBH from the queue. Worker thread releases CBH
back to the main thread queue when done.
Synchronization goes two ways:
1. Work submitted to worker thread is managaed with a mutex and
condition variable based around the work queue.
2. Available CBH ptrs for the main thread have a mutex and condition
variable that manages the CBH queue.
The worker thread is disabled by default, and, when enabled, it will
currently behave and perform as the non-threaded code. This is because
the kNumCommandBuffers const in ContextVk.h is set to 2. With only 2
command buffers, they will be assigned to the inside and outside
RenderPass command buffers respectively. Then, as soon as one is
submitted, the main thread will stall waiting for it to be completed
and put back into the queue mentioned in #2 above.
The next step is to move command submission to the worker thread and
update the number of command buffers so that processing/submission
will occur in parallel with the main thread. Right now there is a
race condition issue when attempting to run in parallel because the
main thread updates and submits the same primary command buffers
that are used in the worker thread, which is in violation of the
Vulkan spec.
The follow-on CL will fix this issue as the main thread will only
touch SecondaryCommandBuffers and the worker thread will be the
only thread touching the primary command buffers.
