Windows: regenerate systray icon when screen resolution changes
When the screen resolution or scale factor changes, then we have to
recreate the system tray icon so that it doesn't get blurry. Such
changes generate a WM_TASKBARCREATED message, which we already handle
through a self-registered message ID to re-add the icon when the task
bar/explorer crashed. So call updateIcon there to recreate the HICON
before adding it again.
For this to work, we have to actually store the QIcon in the already
present (but so far unused) m_icon member, and reset that member before
calling updateIcon, which would otherwise be a no-op.
Fixes: QTBUG-108641
Pick-to: 6.4 6.2
