anv/entrypoints: VkGetDeviceProcAddr returns NULL for core instance commands

af5f2322d0c64 addressed this for extension commands, but the spec mandates
this behavior also for core API commands. From the Vulkan spec,
Table 2. vkGetDeviceProcAddr behavior:

device     pname                            return
----------------------------------------------------------
(..)
device     core device-level command        fp
(...)

See that it specifically states "device-level".

Since the vk.xml file doesn't state if core commands are instance or
device level, we identify device level commands as the ones that take a
VkDevice, VkQueue or VkCommandBuffer as their first parameter.

Fixes test failures in new work-in-progress CTS tests.

v2:
  - Include reference to github issue (Emil)
  - Rebased on top of Vulkan 1.1 changes.

v3:
  - Remove the not in the condition and switch the then/else cases (Jason)
