[vulkan] Representation of Vulkan resources

bug: 111137294
bug: 119104304
bug: 119157982

Even though the intent of the driver is to be as passthrough as
possible, we still need to have custom internal representations of
Vulkan resources:

1. Android Vulkan loader requires HWVULKAN_DISPATCH_MAGIC at the
beginning of dispatchable handles (instance, physical device, device,
queue, command buffer).
2. For non-dispatchable handles, we are going to have some level of
custom work anyway because
    - VkDeviceMemory needs to have special handling for crossing VM
boundary, either with pipe streaming or DMA.
    - Allocation callback support.

+ Rename to Resources.h/cpp, HandleWrappers isn't desriptive enough
