With updated validation layers Vulkan backend is hitting two new
errors. This CL fixes one and works around (WA) another.
Fixes issue where a Buffer used in vkCmdDispatchIndirect() did
not have VK_BUFFER_USAGE_INDIRECT_BUFFER_BIT set so now setting
that usage bit for all buffers.
WA issue where invalid topologies enabled primitiveRestart so
ignoring that VUID initially until complete fix is implemented.
