QmlProfiler: Clean up type selection in statistics model

Browse Source 
The statistics have one extra valid event type: "Main Program". This
should not be mapped to typeId -1, as -1 is the invalid typeId. Map it
instead to std::numeric_limits<int>::max() and remove all the hacks
around it.

Additionally, optimize the selection algorithm for the statistics main
view: We don't need to iterate all types to select one. We can rather
use the fact that the row numbers in the source model match the type
indices (except for the two special ones).
