This changes many interfaces to accept StandardFrames instead of JavaScriptFrames, and use the StackTraceFrameIterator instead of the JavaScriptFrameIterator. Also, the detailed frame information array now contains the script in addition to the function, as wasm frames are not associated to any javascript function. This is a rebase of (https://codereview.chromium.org/2069823003/), since clemensh's internship has ended.
