Enable Detail Flood Fill for All Dyntopo Modes (and UI Tweak)

Flood Fill for All Modes

Dyntopo should allow users to flood fill their mesh without switching detailing modes.

When sculpting using the other detail modes, it can still be useful to flood fill detail. For example, it can provide a good starting point for redoing the details of a sculpt.

This would synergize with another change that I proposed: Detail Flood Fill - Default Hotkey

UI Tweak

Since the detailing mode changes how the detail scale is calculated, I think the detailing mode should appear above detail size, detail percentage, or resolution in the list.

Swapping the location of these two settings, is particularly nice for constant/manual detail since it moves the resolution selection next to the flood fill button.

This tweak is motivated by the first proposed idea since the UI will need to be changed to better accommodate the extra button and slider for relative/brush detail while maintaining a consistent layout across all four modes.

Here is an image showing how the UI could look with the combined changes.
