Fix T84638: Wrong scale for primitives with radius

Creating some primitives allows for a scale value (via python) that will
scale the object accordingly. For objects with a radius parameter
(like cylinders, spheres, etc.) passing a scale different to (1,1,1)
would result in unexpected behavior.

For example:
`>>> bpy.ops.mesh.primitive_uv_sphere_add(radius=2, scale=(1,1,2))`
We would expect this to create a sphere with a radius of 2
(dimensions 4,4,4) and then be scaled *2 along the z-axis
(dimensions 4,4,8). But this would previously create a scaled sphere
with dimensions (2,2,4).

The scale was simply divided by two. Maybe because the "radius"
parameter for creating the primitives was confusingly named "diameter"
(but used as the radius).

The fix adds a scale parameter to `ED_object_new_primitive_matrix`
and also renames the wrongly named "diameter" parameters to "radius".
