Simple stack traces are captured through Isolate::CaptureSimpleStackTrace. Captured frames are stored in a FixedArray, which in turn is stored as a property (using a private symbol) on the error object itself. Actual formatting of the textual stack trace is done lazily when the user reads the stack property of the error object. This would involve many conversions back and forth between index-encoded raw data (receiver, function, offset and code), JS CallSite objects, and C++ CallSite objects. This commit refactors the C++ CallSite class into a Struct class called StackTraceFrame, which is the new single point of truth frame information. Isolate::CaptureSimpleStackTrace stores an array of StackTraceFrames, and JS CallSite objects (now created only when the user specifies custom stack trace formatting through Error.prepareStackTrace) internally only store a reference to a StackTraceFrame.
