LibGfx/ICC: Stop allocating a vector on each call to lerp_nd

Browse source 
While all callers of lerp_nd created a Vector with inline_capacity of 4
to ensure no heap allocation will take place for most inputs, lerp_nd
requested a reference to a Vector with 0 inline_capacity, which meant a
new vector was allocated on each call.
