Add vk_blend_overlay_to_pipe() to translate Vulkan's
blend overlap (VK_BLEND_OVERLAP_*_EXT) to the corresponding
pipe_blend_overlap_mode enum values.
This will be used by drivers implementing VK_EXT_blend_operation_advanced
to convert Vulkan state to driver-internal representation.

Vulkan drivers that use nir_lower_blend need to translate Vulkan enums to the
common (non-Vulkan) versions used in nir_lower_blend. We don't need to duplicate
that boilerplate in every VK driver that uses nir_lower_blend, move panvk's
versions to common code so we can use them in agxv. I suspect powervr wants this
too.
It might be useful to also share the logic to translate vk_color_blend_state
to nir_lower_blend_options wholesale, but panvk wouldn't use it and agxv is
downstream so it wouldn't have any in-tree users. So I'll keep that part
vendored (for now). For now, let's share the easy win of the enum translation.
