Philipp Oeser 58f5b128c9 Fix #102872: Custom Normals Average operator ui shows wrong properties
`Weight` & `Threshold` sliders should **not** show in case of `Type` :
`Custom Normal` and **should** show for both `Type` : `Face Area` &
`Type` : `Corner Angle`

In code, it looks like we are gathering `loop_weight` with `val`.
- this is always 1.0 for `EDBM_CLNOR_AVERAGE_LOOP`
- this is taken from `BM_face_calc_area` for
`EDBM_CLNOR_AVERAGE_FACE_AREA`
- this is taken from `BM_loop_calc_face_angle` for
`EDBM_CLNOR_AVERAGE_ANGLE`

Code then compares not equal those values with given threshold, but for
`EDBM_CLNOR_AVERAGE_LOOP` this will never trigger (since all values are
the same), thus `count` is always zero which makes the effective
`n_weight` always 1. So all loop split normals are averaged for a vertex
with the same weight (seems to make sense to me -- at is just plain
average)

Long story short: the condition to show `Weight` & `Threshold` sliders
is just flipped (these only apply for the methods that take neighbor
faces into account).
