Fix upcast attention dtype error.

Without this fix, enabling the "Upcast cross attention layer to float32" option while also using `--opt-sdp-attention` breaks generation with an error:

```
  File "/ext3/automatic1111/stable-diffusion-webui/modules/sd_hijack_optimizations.py", line 612, in sdp_attnblock_forward
    out = torch.nn.functional.scaled_dot_product_attention(q, k, v, dropout_p=0.0, is_causal=False)
RuntimeError: Expected query, key, and value to have the same dtype, but got query.dtype: float key.dtype: float and value.dtype: c10::Half instead.
```

The fix is to make sure to upcast the value tensor too.

Fixed bugs in the zoom builtin extensions and made the zoom function global

Make override function have the same input parameters with original function

I changed the regular expression and now I always have to select scale from style.transfo

Isolated each instance of applyZoomAndPan, now if you add another element to the page, they will work correctly
