QNSView: Harden logic around platform window access
Some users have reported crashes in -[QNSView mouseEnteredImpl:]
which we believe are due to null m_platformWindow. The stack
traces are like the one below or similar:
0 libqcocoa_dylib QNSView mouseEnteredImpl_ 0x1F
1 appkit NSTrackingArea _dispatchMouseEntered_ 0xA2
2 appkit NSApplication sendEvent_ 0xF4D
3 libqcocoa_dylib QNSApplication sendEvent_ 0x4E
4 libqcocoa_dylib QCocoaEventDispatcher processEvents 0x184
5 qtcore QEventLoop exec 0x19C
6 qtwidgets QDialog exec 0x20B
Moreover, since 2f505b79a49bdf5ba8d084e13ab339bcf956c849, that
member is a QPointer, so we should do more systematic checks.
