Fix T86347: Add Primitive Tool fails for 1x1x1 scale
The Tool stores desired dimensions as `scale` and thus had to half the
scale again in `make_prim_init()` because by default all primitives are
created at a size of 2 in blender.
This worked, but:
- [1] it logged something like size=2, scale=2,2,2 for a 2x2x2 cube
[which does not sound right, it should be size=2 scale=1,1,1]
- [2] it had to make an exception for the case scale is exactly 1x1x1
[this happens when the property is not set specifically, e.g. adding
primitives from the menu]
-- this exception led to double sized primitives being created when the
tool asked for exact dimensions of 1x1x1
Now - instead of compensating in `make_prim_init()` - do this earlier in
the tool itself, see `view3d_interactive_add_modal`, this fixes the bug
and now also correctly logs size=2 scale 0.5,0.5,0.5 for a 1x1x1 cube.
