GHCi debugger: drop record name spaces for Ids

When binding new local variables at a breakpoint, we should create
Ids with variable namespace, and not record field namespace. Otherwise
the rest of the compiler falls over because the IdDetails are wrong.

Fixes #25109

JS: support rubbish static literals (#25177)

Support for rubbish dynamic literals was added in #24664. This patch
does the same for static literals.

compiler: Store ForeignStubs and foreign C files in interfaces

This data is used alongside Core bindings to reconstruct intermediate
build products when linking Template Haskell splices with bytecode.

Since foreign stubs and files are generated in the pipeline, they were
lost with only Core bindings stored in interfaces.

The interface codec type `IfaceForeign` contains a simplified
representation of `ForeignStubs` and the set of foreign sources that
were manually added by the user.

When the backend phase writes an interface, `mkFullIface` calls
`encodeIfaceForeign` to read foreign source file contents and assemble
`IfaceForeign`.

After the recompilation status check of an upstream module,
`initWholeCoreBindings` calls `decodeIfaceForeign` to restore
`ForeignStubs` and write the contents of foreign sources to the file
system as temporary files.
The restored foreign inputs are then processed by `hscInteractive` in
the same manner as in a regular pipeline.

When linking the stub objects for splices, they are excluded from suffix
adjustment for the interpreter way through a new flag in `Unlinked`.

For details about these processes, please consult Note [Foreign stubs
and TH bytecode linking].

Metric Decrease:

Rework built-in and punned names (#25174, #25179, #25180, #25182)

This patch rewrites part of the logic for dealing with built-in and
punned names, making it more principled and fixing a few bugs.

* Kill off filterCTuple. Its purpose was to improve pretty-printing of
  constraint tuples, and the appropriate place for this is namePun_maybe.

* Remove unitTyCon, unboxedUnitTyCon, and soloTyCon from wiredInTyCons.
  Their inclusion in the list was a workaround for shoddy logic in
  lookupOrigNameCache. Now we treat tuples of all arities uniformly.

* In isBuiltInOcc_maybe, only match on actual built-in syntax, e.g. "FUN"
  shouldn't be there (#25174). Also take ListTuplePuns into account (#25179).

* When matching OccNames, use the ShortByteString directly to avoid
  potentially costly conversions to ByteString and String.

* Introduce isInfiniteFamilyOrigName_maybe, a purpose-built helper for
  looking up tuples/sums in the OrigNameCache. This clears up the previously
  convoluted relation between the orig name cache and built-in syntax.

* Fix #13776 directly in the Outputable RdrName instance instead of the
  workaround in thOrigRdrName. Reuse lookupOrigNameCache to eliminate
  the need for isPunOcc_maybe.

* Classify MkSolo and MkSolo# as UserSyntax, thus fixing whole-module
  reexports (#25182).

* Teach valid-hole-fits about tuples, unboxed tuples, and unboxed sums,
  up to a certain arity (#25180).

* Drop the unnecessary special case for unary constraint tuples in the
  type checker (finish_tuple). It was a workaround for the lack of CSolo.

* Update Notes and other comments, add tests.
