Allow resetting background colour of wxHtmlContainerCell.

Don't use m_UseBkColour flag which remained always set once
SetBackgroundColour() had been called, but just rely on m_BkColour itself
being valid to determine whether we should use it. This allows to reset the
background colour after setting it.

Closes #15287.
