sw floattable, delete UI: fix unfloat button for cant-split frames

Open sw/qa/extras/uiwriter/data/unfloatable_floating_table.odt, select
the TextFrame, click on the "unfloat" button that appears, then nothing
happens.

This is a problem since commit 51379fb3d46e5891bdaea0122bd62b0753663da3
(weld writer's FrameControl MenuButtons, 2020-12-03), the old
MouseButtonDown() callback is never invoked.

Fix the problem similar to what SwHeaderFooterWin does, which works:
instead of overriding the dead MouseButtonDown(), explicitly connect the
click handler to the weld::Button widget.

Also adjust SwFlyFrame::ActiveUnfloatButton() to use the welded
callback, this way CppunitTest_sw_uiwriter2's testUnfloating covers the
fix.
