Reland "Check FP16 support on vulkan backend"

This reverts commit 0357eed7de15e901d14f6149e91bfe03d86958de
and reland commit bdc05c3d5fef780382c3fd5e5ebcb14bd929819a.

The Vulkan-Loader has a bug where if the instance is created
with Vulkan 1.1 and not the promoted extensions, it will skip
emulation and if the ICD doesn't support Vulkan 1.1 nor the
extensions. Enable the promoted extensions, even when creating
a Vulkan 1.1 instance.
