Add `Data.Functor.unzip`

This function is currently present in `Data.List.NonEmpty`, but `Data.Functor`
is a better home for it. This change was discussed and approved by the CLC
at https://github.com/haskell/core-libraries-committee/issues/88.

linker: fix linking with aligned sections (#23066)

Take section alignment into account instead of assuming 16 bytes (which
is wrong when the section requires 32 bytes, cf #23066).

Change hostSupportsRPaths to report False on OpenBSD

OpenBSD does support -rpath but ghc build process relies on some
related features that don't work there. See ghc/ghc#23011

Restructure IPE buffer layout

Reference ticket #21766

This commit restructures IPE buffer list entries to not contain
references to their corresponding info tables. IPE buffer list nodes now
point to two lists of equal length, one holding the list of info table
pointers and one holding the corresponding entries for each info table.
This will allow the entry data to be compressed without losing the
references to the info tables.

Add IPE compression to configure

Reference ticket #21766

Adds an `--enable-ipe-data-compreesion` flag to the configure script
which will check for libzstd and set the appropriate flags to allow for
IPE data compression in the compiler

IPE data compression

Reference ticket #21766

When IPE data compression is enabled, compress the emitted IPE buffer
entries and decompress them in the RTS.

Fix libzstd detection in configure and RTS

Ensure that `HAVE_LIBZSTD` gets defined to either 0 or 1 in all cases
and properly check that before IPE data decompression in the RTS. See
ticket #21766.

Fix byte order of IPE data, fix IPE tests

Make sure byte order of written IPE buffer entries matches target.

Make sure the IPE-related tests properly access the fields of IPE buffer
entry nodes with the new IPE layout.

This commit also introduces checks to avoid importing modules if IPE
compression is not enabled.

See ticket #21766.

Fix IPE data decompression buffer allocation

Capacity of buffers allocated for decompressed IPE data was
incorrect due to a misuse of the `ZSTD_findFrameCompressedSize`
function. Fix by always storing decompressed size of IPE data in IPE
buffer list nodes and using `ZSTD_findFrameCompressedSize` to determine
the size of the compressed data.

See ticket #21766

Add optional dependencies to ./configure output

Changes the configure script to indicate whether libnuma, libzstd, or
libdw are being used as dependencies due to their optional features
being enabled.

Add IPE-enabled builds to CI

- Adds an IPE job to the CI pipeline which is triggered by the ~IPE label
- Introduces CI logic to enable IPE data compression
- Enables uncompressed IPE data on debug CI job
- Regenerates jobs.yaml

MR https://gitlab.haskell.org/ghc/ci-images/-/merge_requests/112 on the
images repository is meant to ensure that the proper images have
libzstd-dev installed.

Update user's guide and release notes

Add mention of IPE data compression to user's guide and the release
notes for 9.8.1. Also note the impact compression has on binary size in
both places.

Optional static linking of libzstd

Allow for libzstd to be statically linked with a
`--enable-static-libzstd` configure flag. Not supported on darwin due to
