Describe the issue
Currently the Paragraph block features a "Typography" panel within the Settings sidebar for font size and line height, as well as a separate "Text settings" panel for the drop cap ToggleControl. I propose that we consolidate these panels into one, as they're all typographic controls.

Suggested behavior
Move the Drop cap control to the Typography panel within the Paragraph block's setting sidebar. This will simplify the sidebar by removing an unnecessary panel.
