The statistics are now also filtered by the selected threads. If no
thread is selected, the statistics are presented for all threads combined.
This fixes a bug with double counted events, too.

Add a new dropdown menu to select which threads should be displayed.
If no threads are selected, all are shown (this is why the word
'restriction' was chosen). At the moment this only affects the
timeline view, see the follow up for the statistics view.

Add more information in the details popup for counters
(e.g. CPU usage) like current value, min and max values.
Also fixes that the start time of a counter element wasn't
displayed.

Column::COUNT should not show up as actual column, but the compiler
doesn't know.

This new plugin adds a viewer for Chrome Trace Format (CTF) files
(aka Trace Event Format). It uses the same UI components as the
QML Profiler timeline and the Perf Profiler.
The Trace Event Format is generated by different kinds of tracing tools.
Usually the files are display with the trace-viewer, built into Chrome
(chrome://tracing). This plugin was developed because of the high memory
usage of trace-viewer, which makes it difficult to use with trace files
bigger than 100 MB.
The plugin fully supports all event types used in data generated by
LTTng, converted to CTF by https://github.com/KDAB/ctf2ctf.
Some of the more advanced event types used for example in Android system
traces, though, are not supported. The viewer will silently ignore
unsupported event types.
Supported Event Types:
- Begin, End, Duration and Instant events
- Counter events (graphs)
- Metadata events (process and thread name)
The plugin uses nlohmann/json instead of QJson because of the ~128 MB
object size limit by QJson.
