Add support for stack traces containing wasm frames in package:source_map_stack_trace

[mkustermann]

To get nicer stack traces we probably want to add support for parsing JS stacks that contain wasm frames to package:source_map_stack_trace.

I've updated stack_trace to parse Wasm frames in Chrome, Firefox, Safari.

No changes needed in this package as there's nothing Wasm specific in mapping frame lines and columns to sources.

We can release a new version of stack_trace with the changes, and then bump the dependency in this package, then close this issue.
