This is a step toward making the trace manager non-virtual. It should
just juggle the storages for types and events, and manage the threads to
access them. It doesn't need to know what exactly it stores.

When we replay events we want to keep this constant and pass it to the
event receivers as separate entity. This way we can move the replaying
to a separate thread.
When loading we will have a similar situation, but then the loading
thread will create a new type storage and later assign that to the trace
manager.

We always want either the total number of event types or one specific
type. There is no need to expose the fact that we keep them as a vector.
Also, use int as the type of the "number" methods as that aligns better
with Qt containers, and rename the methods. We don't need to state the
fact that we've loaded the events and types at some point.

We want to get rid of the big master list of QmlEvent in
QmlProfilerDataModel, as that gets very large for longer traces. In
order to reduce the dependencies on that list we load the events on the
fly into the child models while they are being received, rather than
having the child models query QmlProfilerDataModel for the event list
later.
As the trace client so far only emitted rangedEvent() for complete
ranges we run into problems with models that need their events sorted.
The rangedEvent() signals were sorted by end time, rather than start
time which makes it inconvenient to analyze them in a stack based way,
for aggregation. This is solved by passing on all the details from the
trace client to the models, with the QmlProfilerDataModel aggregating
the type information before having the events dispatched to the child
models.

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.
