Use unsatisfiable for missing methods w/ defaults

When a class instance has an Unsatisfiable constraint in its context
and the user has not explicitly provided an implementation of a method,
we now always provide a RHS of the form `unsatisfiable @msg`, even
if the method has a default definition available. This ensures that,
when deferring type errors, users get the appropriate error message
instead of a possible runtime loop, if class default methods were
defined recursively.

Fixes #23816

nonmoving: Drop dead debugging utilities

These are largely superceded by support in the ghc-utils GDB extension.

nonmoving: Refactor management of mark thread

Here we refactor that treatment of the worker thread used by the
nonmoving GC for concurrent marking, avoiding creating a new thread with
every major GC cycle. As well, the new scheme is considerably easier to
reason about, consolidating all state in one place, accessed via a small
set of accessors with clear semantics.

testsuite: Skip T23221 in nonmoving GC ways

This test is very dependent upon GC behavior.

ghc-heap: Don't expose stack dirty and marking fields

These are GC metadata and are not relevant to the end-user. Moreover,
they are unstable which makes ghc-heap harder to test than necessary.
