Animation: Paste Keys in Graph Editor with value offset

Browse Source 
Extend the `GRAPH_OT_paste` operator with an enum to define the value offset.

Options are:

| Option              | Effect                                                                        |
| ------------------- | ----------------------------------------------------------------------------- |
| No Offset           | use the same key values as the copied keys                                    |
| Cursor Value        | align the leftmost key with the cursor value                                  |
| Current Frame Value | Evaluate the curve under the cursor align the leftmost key with it            |
| Right Key           | Align the rightmost key with the first key that is to the right of the cursor |
| Left Key            | Align the leftmost key with the first key that is to the left of the cursor   |
