    remove support for BITMASK in vcl backends

So the code that I removed had
    if (meFormat == DeviceFormat::BITMASK)
        SetAntialiasing( AntialiasingFlags::DisableText );
in the
    VirtualDevice::ImplInitVirDev
method.

Possibly we will need to make similar fixes in other places that used
BITMASK, but this looks like the only spot that really needs it.

No idea exactly how this line of code relates to the observed bug
though.
