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].

git: remove a.out and include it in .gitignore

a.out is a configure script byproduct. It was mistakenly checked into
the tree in !13118. This patch removes it, and include it in
.gitignore to prevent a similar error in the future.

JS: add basic support for POSIX *at functions (#25190)

openat/fstatat/unlinkat/dup are now used in the recent release of the
`directory` and `file-io` packages.

As such, these functions are (indirectly) used in the following tests
one we'll bump the `directory` submodule (see !13122):
- openFile008
- jsOptimizer
- T20509
- bkpcabal02
- bkpcabal03
- bkpcabal04

Update directory submodule to latest master

The primary reason for this bump is to fix the warning from `ghc-pkg
check`:

```
Warning: include-dirs: /data/home/ubuntu/.ghcup/ghc/9.6.2/lib/ghc-9.6.2/lib/../lib/aarch64-linux-ghc-9.6.2/directory-1.3.8.1/include doesn't exist or isn't a directory
```

This also requires adding the `file-io` package as a boot library (which
is discussed in #25145)

Fixes #23594 #25145

Fix aarch64-alpine target platform description

We are producing bindists where the target triple is

aarch64-alpine-linux

when it should be

aarch64-unknown-linux

This is because the bootstrapped compiler originally set the target
triple to `aarch64-alpine-linux` which is when propagated forwards by
setting `bootstrap_target` from the bootstrap compiler target.

In order to break this chain we explicitly specify build/host/target for
aarch64-alpine.

This requires a new configure flag `--enable-ignore-` which just
switches off a validation check that the target platform of the
bootstrap compiler is the same as the build platform. It is the same,
but the name is just wrong.

These commits can be removed when the bootstrap compiler has the correct
target triple (I looked into patching this on ci-images, but it looked
hard to do correctly as the build/host platform is not in the settings
file).

Fixes #25200

Only export defaults when NamedDefaults are enabled (#25206)

This is a reinterpretation of GHC Proposal #409 that avoids a breaking
change introduced in fa0dbaca6c "Implements the Exportable Named Default proposal"

Consider a module M that has no explicit export list:

	module M where
	default (Rational)

Should it export the default (Rational)?

The proposal says "yes", and there's a test case for that:

	default/DefaultImport04.hs

However, as it turns out, this change in behavior breaks existing
programs, e.g. the colour-2.3.6 package can no longer be compiled,
as reported in #25206.

In this patch, we make implicit exports of defaults conditional on
the NamedDefaults extension. This fix is unintrusive and compliant
with the existing proposal text (i.e. it does not require a proposal
amendment). Should the proposal be amended, we can go for a simpler
solution, such as requiring all defaults to be exported explicitly.

Test case: testsuite/tests/default/T25206.hs

simplifier: Fix space leak during demand analysis

The lazy structure (a list) in a strict field in `DmdType` is not fully
forced which leads to a very large thunk build-up.

It seems there is likely still more work to be done here as it seems we
may be trading space usage for work done. For now, this is the right
choice as rather than using all the memory on my computer, compilation
just takes a little bit longer.

See #25196

Add missing parenthesizeHsType in cvtp's InvisP case

We need to ensure that when we convert an `InvisP` (invisible type pattern) to
a `Pat`, we parenthesize it (at precedence `appPrec`) so that patterns such as
`@(a :: k)` will parse correctly when roundtripped back through the parser.

Fixes #25209.
