LineArt: Remove "soft selection" option.

After some back and forth with the GP module and some artists, this
option was deemed not that useful. The use case was considered too
obscure so we'll remove it.

It is still posible to have this functionality by using the vertex
weight modiifers or manually clamping the weights.
