This file changes the non-dispatchable Vulkan handle types. We want to
use some of these handles in utils/VulkanSwapChain.cpp so it needs to
have access to it. The file could include
backend/vulkan/vulkan_platform.h but it seems a bit cleaner to move the
header in common/ instead with a warning if the Vulkan backend isn't
enabled.
In Vulkan images are created in no particular layout and must be
transitioned before they can be used. This didn't appear before because
the test were creating the textures with not initial usage and then
transitioned them. This isn't the case with InputStateTest, which is
what uncovered this issue.
This as this is the first command handled by the Vulkan backend, this
commit also introduces the b:✌️:CommandBUffer class and implements
b:✌️:Queue::Submit.
Also enables the BufferSetSubData tests that are now passing on Vulkan
even though the buffer transitions are unimplemented.
This introduce a new FencedDeleter service as part of the Device
objects that tracks when resources are no longer used and deletes them.
BufferVk takes advantage of this to defer the deletion of its handle
that was previously incorrectly delete directly in ~BufferVk.
On 32 bit Vulkan typedefs these handles to uint64_t which breaks
function overload resolution. Replace the
VK_DEFINE_NON_DISPATCHABLE_HANDLE and VK_NULL_HANDLE defines to be
opaque C++ types with the same capabilities.
