David Aurelio f361f99f53 Add sourcemap support for asset-based random access bundles
Summary:This adds support for source maps that can be used for “random access modules” / “unbundles”

- source maps contain an extra custom field: `x_facebook_offsets`
- this field maps module IDs to line offsets
- the source map is built as if all files were concatenated

Decoding/symbolication works as follows:
- when decoding a stack trace, and a stack frame comes from a filename that contains only numbers and ends with `.js`, look up the additionally needed line offset in the offset map and add it to the original line of the stack frame.
- consume the source map as usual
