[Bug 379660] Collapse template arguments in flamegraph using checkbox

[aravindev]

This PR is a duplicate of #34 but addresses all the comments since it has been dormant for a while.

I have created a checkbox that can be used to toggle template elision such that the template arguments can optionally be collapsed. This feature is disabled by default.

@milianw Since you were the original reviewer, could you take a look?

Sorry for the delay, I'll have a look now

So, this code is potentially a first step but I think it should be closer to the approach we use in hotspot - see e.g.:

https://github.com/KDAB/hotspot/blob/master/src/util.cpp#L135

generally, we would collapse these everywhere - not just in the flamegraph. the same logic should be used in the tables, and we don't want to do the collapse all the time for view purposes only
