debug_server: Remove duplicate setting of B_FLOATING_ALL_WINDOW_FEEL.

debug_server: Make crash prompt appear above all other windows.

With B_MODAL_WINDOW, others can be brought in front. But with
B_MODAL_WINDOW_LOOK plus B_FLOATING_ALL_WINDOW_FEEL, it will
retain its current appearance, but always stay on top of all other
windows.

Since debug_server does not have a Deskbar entry, this will prevent
such windows from getting "lost" and then having to minimize all others
in order to find them (or forgetting about them altogether by accident.)

debug_server: Restore <algorithm> include to appease GCC2.

debug_server: Make use of BControlLook::ComposeIconSize.

DebugWindow: improve layout

Fixes #15155.

debug_server: build a new debug window

Use radio buttons laid out vertically so that locales with long labels
(no short word for "write core file") can still look nice. This is open
for experiment, buttons laid out vertically are another option. At least
now we have a window t work from, as BAlert doesn't cut it here.

While I'm at it, use a ladybug icon for this one, so it's visibly
different from normal application alerts.
