wxMSW: Fix wxToolBar rendering with double-buffering

Browse Source 
An old check - used for reasons that no longer apply - was preventing
correct rendering of wxToolBar background in wxMSW. Fix this by removing
the obsolete check.

See #9666 for the original reason for the check.

(cherry picked from commit 3a7951db2b)
