Fix: Make textarea fill the area available instead of being resizable. (#6190)

## Summary

Invert the sizing of textareas. They now grow based on the container
instead of being independently resizable.

## Review Focus

Tested the behavior in Note, Markdown Note, CLIP Text Encode, and
Subgrpahs with promoted mutliline text widgets.

Anything else that might break with this?
