ref(processor): Fold occurences of property names in function_name

[kamilogorek]

Fold multiple consecutive occurrences of the same property name into a single group, excluding the last component.

foo | foo
foo.foo | foo.foo
foo.foo.foo | {foo#2}.foo
bar.foo.foo | bar.foo.foo
bar.foo.foo.foo | bar.{foo#2}.foo
bar.foo.foo.onError | bar.{foo#2}.onError
bar.bar.bar.foo.foo.onError | {bar#3}.{foo#2}.onError
bar.foo.foo.bar.bar.onError | bar.{foo#2}.{bar#2}.onError

This is mostly done for React, where some frames have function name like <object>.children.children.children.onSubmitError when function is a prop passed down the component stack.

nice, though I thought you wanted to do that as part of the UI?
I think native does have some kind of function name cleaning going on, and you can toggle in the UI if you want to have clean functions or full functions. The clean version is used for grouping there.

Asked @mitsuhiko and he pointed out that we can do it here instead of in the UI.
I've seen there's normalize_stacktraces_for_grouping which does the trimming as well, but Im not sure what are the consequences of it.
It'd be great to get an input from @untitaker or @jan-auer as well.

[mitsuhiko]

I'm okay with that but for the record you can do f"{{{p[0]}#{len(p)}}}".

Need more cowbell braces.

replit was not happy about this syntax for some reason, so I went with codes directly

[mitsuhiko]

I prefer this being done in ingestion so the response from the API is consistent everywhere including emails, notifications and whatnot.
