Vulkan: Add feature avoid HOST_VISIBLE and DEVICE_LOCAL combination 

Discrete GPUs device local memory usually is not CPU accessible. This
adds a feature flag to control that.

Fixed bug in BufferVk that when mapRangeImpl is called from angle
internal, unmapImpl was using front end mapping parameters that is
incorrect. We have to cache the mapping parameters in the backend to
hangle the mapRangeImpl/unmapImpl calls from internal.

Fixed the test bug in ComputeShaderTest.BufferImageBufferMapWrite that
we are calling glMapBufferRange with GL_MAP_READ_BIT but are actually
writing to the map pointer. This should result in undefined behavior per
spec.

Fixed the test bug in GLSLTest.* that VerifyBuffer calls
glMapBufferRange, but was giving incorrect length which result in data
only been partially copied. This bug was hidden due to previously all
buffers are CPU accessible and there is no copy needed.

Fixed the test bug in ReadPixelsPBOTest.* and ReadPixelsPBONVTest.* that
calls glMapBufferRangeEXT, but was giving incorrect length which result
in data only been partially copied. This bug was hidden due to
previously all buffers are CPU accessible and there is no copy needed.

Added new skipped syncval messages. Because this CL triggers a
copyToBuffer call for some of the buffers and that changes the syncval
message signature for the same reasons (i.e, feedback loop or synval
does not know the exact range of buffer been used for vertex buffers
etc).
