Currently there are two ways wasm locations are represented in the
inspector. This remains unchanged for now. Also, currently there are
multiple ways location is represented within V8, with the line number
sometimes being a function index and sometimes being 0, and the column
number being a byte offset which is sometimes function relative and
sometimes module relative. With this change, the line number is never
used within V8 (it is always 0), and the column number is always a
byte offset from the beginning of the module. This simplifies
translation logic and keeps it in one place, and will simplify future
changes to wasm location representation in the inspector API.

Currently, in wasm-function stack traces, v8 displays the decimal offset
from the start of the function. However, the WebAssembly WebAPI
specification says that it should be a hex offset into the module.
This change makes the stack trace display with hex module offsets, as
well as fixing all the unit tests that depended on the old behaviour.

We noticed that almost every call site were loading both files,
the split isn't necessary anymore.
In some message tests, removed the absolute line number to allow future
changes.

This way, we can also check the return code of d8. We currently have a
bug (6981) which makes failing tests not being detected, even though
the failure message is (sometimes) being printed.
After this refactoring, we can write tests for our mjsunit test
functions.
