QWindowsWindow: Use updated windowFlags for framelessWindow query

Browse Source 
Currently the internal flags of QWindow are not up-to-date when querying
them during QWindowsWindow::setFlags with QWindow::flags(). QWindow
updates its flags after QWindowsWindow returns from setFlags. This patch
adds a getter, to query the updated internal state of
Qt::FrameLessWindowHint flag from QWindowsWindow's m_data.flags.

This is needed due to QWindowsWindow is calling SetWindowPos, which
immediately enters the WndProc without access to the newly set flags.

Pick-to: 6.8 6.7
