Consider to use stackframe's name in "exclude locations"

[weinand]

Testing #141348

Today exclude locations are based on the file name which is not very informative:

Including the stackframe's name, e.g. the function/method could improve the readability:

foo: callers.js:11:5 > hello: callers.js:3:9
bar: callers.js:20:5 > hello: callers.js:6:9

The same could be done for the context menu action: "Exclude Caller" -> "Exclude Caller 'foo'"

(BTW, I love Safari's feature to OCR and copy strings directly from images)
