QmlProfiler: Add a QmlTypedEvent and extend QmlEvent

Browse Source 
The QmlTypedEvent is mainly useful to read a generic QmlEvent and
QmlEventType from a QPacket. QmlEventType has a stream operator to do
exactly that. QmlEvent also gets further options to store 32-bit data
in addition to 64- and 8-bit data. Also, with the more generic storage
layout we can reduce the memory consumption of range events by 50%.
This comes at the cost of additional memory allocations for non-range
events, but as non-range events are significantly less frequent than
range events, this is a good tradeoff. Finally the new storage layout
lends itself to efficient serialization, which will help when
developing new storage and transfer formats for QML traces.
