feat: Add file and line numbers to exception traceback

[Christopher-Chianelli]

• CPython does not expose any sane way to set the traceback
  of an exception that does not orginate from a CPython
  exception. In particular, traceback must be an
  internal Traceback type, and that Traceback type
  cannot be constructed without using internal frame
  and code types, which also cannot be constructed.

• To get around this, we exploit the traceback module,
  which does not care about types and only care about
  interfaces. This allow us to use our own fake frame
  and code classes that match their interface.

• We exploit object.new to create an instance of
  TracebackException without calling its constructor,
  and set all its fields manually

• To set the stack field, we use StackSummary.from_list.
  with the Java traceback.

• Python 3.10 has a quirk: it calls RERAISE in
  the finally block corresponding to an except
  block. That finally immediately calls RERAISE,
  but TOS is a type, so that exception loses both
  it cause and message. So work around this,
  we deviate a bit from how the code apparently
  works

  • After finally branch is taken, stack is
    <block (3 items)> traceback, exeception, exception
    instead of
    <block (3 items)> traceback, exeception, type
  • JUMP_IF_NOT_EXEC_MATCH is now an instanceof
    instead of issubclass

  This works since Python pops off all these values when
  actually entering the code for an except block, and
  JUMP_IF_NOT_EXEC_MATCH is the only opcode that can
  be encountered.

Minor typo, otherwise LGTM.
