drm/i915/uapi: add probed_cpu_visible_size
Userspace wants to know the size of CPU visible portion of device
local-memory, and on small BAR devices the probed_size is no longer
enough. In Vulkan, for example, it would like to know the size in bytes
for CPU visible VkMemoryHeap. We already track the io_size for each
region, so plumb that through to the region query.
v2: Drop the ( -1 = unknown ) stuff, which is confusing since nothing
can currently ever return such a value.
