Currently all DisplayVk implementations depend on VK_KHR_swapchain and
VK_KHR_surface extensions. When running Chromium on Fuchsia these
extensions are never used (content is shown on the screen using
ImagePipe API without dependency on swapchain). ANGLE still depended
on these extensions for DisplayVkFuchsia.
This CL adds DisplayVkNull, which allows to run ANGLE without dependency
on swapchain. It's usable only offscreen and cannot present content on
a surface.

  GetAllocationCallbacks() causes a "unrelated cast" error

angle_enable_vulkan_validation_layers is false on is_mac,
so it looks like they were built by accident. Guard the dep
on $angle_root/src/common/vulkan:vulkan_validation_layers by
angle_enable_vulkan_validation_layers instead of angle_enable_vulkan,
and only define the target if angle_enable_vulkan_validation_layers
is true (because src/common/vulkan/BUILD.gn gets loaded due to deps
on other targets in it, and when a .gn file is loaded all the
targets in it get defined).

Since vulkan_validation_layers doesn't currently build on
arm macs, this happens to fix a build problem there, but it
also makes the build on intel macs a bit smaller.

This sidesteps comment 13 on the bug. If we ever want to use
the validation layers on mac, we'll have to do a real fix then.

Unfortunately this was broken by 605af42e ("Vulkan: Move ICD overrides

This adds an unconditional dependency on the layers to tests. Tests
don't respect angle_enable_vulkan_validation_layers, so we need to ship
