Modeling: Add Auto Normalize when Assigning vertex weights

Browse Source 
Part of #135062.

This PR adds an Auto Normalize option in the Vertex Group panel that
when checked will normalize the other deform-bone vertex groups' weights
when assigning the weight of a deform-bone vertex group. For example if
a selected vertex has the following weights:

| Name    | Weight |
|---------|--------|
| Group 1 | 0.2    |
| Group 2 | 0.2    |
| Group 3 | 0.6    |

And the user selects Group 3, checks the Auto Normalize checkbox, sets
the weight to 0.8, and clicks Assign, the new weights will be:

| Name    | Weight |
|---------|--------|
| Group 1 | 0.1    |
| Group 2 | 0.1    |
| Group 3 | 0.8    |
