Use WS_EX_CONTROLPARENT for wxStaticBox in wxMSW.

This doesn't change anything currently but it seems correct to use this style
with wxStaticBox as it can now contain other windows (and so be "control
parent"), so it could allow Windows or other programs checking for this style
to handle it more correctly.
