Protect global variable g_pointIdMap with mutexes
The evdev touch handler is thread based and calls
QWindowSystemInterface::handleTouchEvent. The global variable
in qwindowsysteminterface.cpp is used without being protected by mutexes
which causes data loss and crashes when multiple touch screens are used.
Fixes: QTBUG-63584
