Use more modern appearance for wxMSW wxTreeCtrl by default

Browse Source 
Change wxTreeCtrl default style under wxMSW to make it look more
up-to-date by default: use twisting buttons and full-row highlight and
don't display connector lines.

Using wxTR_LINES_AT_ROOT together with wxTR_NO_LINES may look odd but it
is needed because without wxTR_LINES_AT_ROOT, the buttons would not be
displayed.

Also update wxTreeCtrl screenshot in the docs.

Closes #23844.
