Vulkan: De-couple Program from VertexArrayVk dirtyiness.
The VertexArrayVk is responsible for filling out the packed shader
input info in ANGLE's packed PipelineDesc info structure. This
packed info structure is used for Pipeline init and caching lookup.
The prior design had this info depend on the active inputs in the
current Program. This was undesirable because then, on a Program
change, the ContextVk would have to call into the VertexArrayVk
to invalidate this info.
Instead, keep a working copy of the VertexArrayVk bits and only
update the bits corresponding to dirty vertex attributes. This
simplifies the cached state management a little bit for ContextVk.
This also means we don't have to update the cached copy in the
VertexArray on a change in VertexArray binding.
