Basic changes:

* Change `catch` function to propagate exceptions using the
  WhileHandling mechanism.
* Introduce `catchNoPropagate`, which does the same as before, but
  passes an exception which can be rethrown.
* Introduce `rethrowIO` combinator, which rethrows an exception with a
  context and doesn't add a new backtrace.
* Introduce `tryWithContext` for a variant of `try` which can rethrow
  the exception with it's original context.
* onException is modified to rethrow the original error rather than
  creating a new callstack.
* Functions which rethrow in GHC.Internal.IO.Handle.FD,
  GHC.Internal.IO.Handle.Internals, GHC.Internal.IO.Handle.Text, and
  GHC.Internal.System.IO.Error are modified to not add a new callstack.

on wasm, by making runWorkerLimit always behave single-threaded. This
avoids introducing the jobserver logic into the final wasm module and

This reuses the upsweep step's infrastructure to process batches of
modules in parallel.

I benchmarked this by running `ghc -M` on two sets of 10,000 modules;
one with a linear dependency chain and the other with a binary tree.
Comparing different values for the number of modules per thread
suggested an optimum at `length targets `div` (n_cap * 2)`, with results
similar to this one (6 cores, 12 threads):

```
Benchmark 1: linear 1 jobs
  Time (mean ± σ):      1.775 s ±  0.026 s    [User: 1.377 s, System: 0.399 s]
  Range (min … max):    1.757 s …  1.793 s    2 runs

Benchmark 2: linear 6 jobs
  Time (mean ± σ):     876.2 ms ±  20.9 ms    [User: 1833.2 ms, System: 518.6 ms]
  Range (min … max):   856.2 ms … 898.0 ms    3 runs

Benchmark 3: linear 12 jobs
  Time (mean ± σ):     793.5 ms ±  23.2 ms    [User: 2318.9 ms, System: 718.6 ms]
  Range (min … max):   771.9 ms … 818.0 ms    3 runs
```

Results don't differ much when the batch size is reduced to a quarter
of that, but there's significant thread scheduling overhead for a size
of 1:

```
Benchmark 1: linear 1 jobs
  Time (mean ± σ):      2.611 s ±  0.029 s    [User: 2.851 s, System: 0.783 s]
  Range (min … max):    2.591 s …  2.632 s    2 runs

Benchmark 2: linear 6 jobs
  Time (mean ± σ):      1.189 s ±  0.007 s    [User: 2.707 s, System: 1.103 s]
  Range (min … max):    1.184 s …  1.194 s    2 runs

Benchmark 3: linear 12 jobs
  Time (mean ± σ):      1.097 s ±  0.006 s    [User: 2.938 s, System: 1.300 s]
  Range (min … max):    1.093 s …  1.101 s    2 runs
```

Larger batches also slightly worsen performance.

Instead, we use a dedicated DelayedError, which is emitted
systematically on submultiplicity checks, but is suppressed if we can
indeed solve the submultiplicity constraint with a reflexivity
coercion.

This way, we don't have to return anything from `tcSubMult`, which now
looks like a regular constraint check, the rest is implementation
detail. This removes all of the strange boilerplate that I'd been
struggling with under the previous implementation. Even if
submultiplicity checks are not properly constraints, this way it's
contained entirely within a `WantedConstraint`. Much more pleasant.

Closes #25128.
