Track in-scope variables in ruleCheckProgram

This small patch fixes #24726, by tracking in-scope variables
properly in -drule-check.  Not hard to do!

Add a couple more HasCallStack constraints in SimpleOpt

Just for debugging, no effect on normal code

driver: always merge objects when possible

This patch makes the driver always merge objects with `ld -r` when
possible, and only fall back to calling `ar -L` when merge objects
command is unavailable. This completely reverts !8887 and !12313,
given more fixes in Cabal seems to be needed to avoid breaking certain
configurations and the maintainence cost is exceeding the behefits in
this case :/

wasm: use scheduler.postTask() for context switch when available

This patch makes use of scheduler.postTask() for JSFFI context switch
when it's available. It's a more principled approach than our
MessageChannel based setImmediate() implementation, and it's available
in latest version of Chromium based browsers.

tests: Widen acceptance window for dir and so size tests

These are testing things which are sometimes out the control of a GHC
developer. Therefore we shouldn't fail CI if something about these
dependencies change because we can't do anything about it.

It is still useful to have these statistics for visualisation in grafana
though.

Ticket #24759

Disable rts_so test

It has already manifested large fluctuations and destabilising CI

Fixes #24762

unboxedSum{Type,Data}Name: Use GHC.Types as the module

Unboxed sum constructors are now defined in the `GHC.Types` module, so if you
manually quote an unboxed sum (e.g., `''Sum2#`), you will get a `Name` like:

```hs
GHC.Types.Sum2#
```

The `unboxedSumTypeName` function in `template-haskell`, however, mistakenly
believes that unboxed sum constructors are defined in `GHC.Prim`, so
`unboxedSumTypeName 2` would return an entirely different `Name`:

```hs
GHC.Prim.(#|#)
```

This is a problem for Template Haskell users, as it means that they can't be
sure which `Name` is the correct one. (Similarly for `unboxedSumDataName`.)

This patch fixes the implementations of `unboxedSum{Type,Data}Name` to use
`GHC.Types` as the module. For consistency with `unboxedTupleTypeName`, the
`unboxedSumTypeName` function now uses the non-punned syntax for unboxed sums
(`Sum<N>#`) as the `OccName`.

Fixes #24750.
