Refactor - Error handling

[Lichtso]

Stops heap allocating errors for efficiency and removes fields from runtime errors for layout stability.
The fields of these errors are mostly redundant and can be retrieved by other means anyway.
Sometimes they are completely pointless such as the pc field for AccessViolation which syscalls always set to 0.
The address where the exception occurred can now be read from the VM (see #529).
Also, we have much better debugging support now, so we don't need to rely on these fields for diagnosis anymore.
