The workflow allows users to restrict what parts are being built. For
example, `installer-i686` will build only the 32-bit installer, not the
64-bit one nor any MinGit flavor.
However, this logic was not extended when introducing support for ARM64:
Instead, we _also_ built the ARM64 installer when the user asked for
`installer-i686`.
Let's allow restricting to `installer-i686` _without_ building the ARM64
version, and allow restricting to `installer-arm64` _just_ for the ARM64
version.

GitHub workflows run in agents that have quite a bit of stuff in their
`PATH`, e.g. Chocolatey. To make sure that those bits and pieces are
_not_ used to build the artifacts, let's whittle down the `PATH` to
contain the bare minimum.

When building the Pacman packages, we technically do not need the full
`build-installers` artifact (which is substantially larger than the
`makepkg-git` artifact). However, the former is already cached and
includes the latter's files. And it is _so_ much faster to download the
cached (larger) artifact than to download the smaller `makepkg-git`
artifact from Azure Pipelines.

With this change, users can specify the branch and repository from which
they want to build Git for Windows' artifacts, via the `ref` and
`repository` inputs.
This allows e.g. building `refs/heads/seen` of `git/git` (even if no
`git-artifacts` workflow is configured in that repository), or
`refs/pull/<number>/merge` for a given Pull Request.

Users can now specify which artifacts they want to build, via the
`build_only` input, which is a space-separated list of artifacts. For
example, `installer portable` will build `installer-x86_64`,
`installer-i686`, `portable-x86_64` and `portable-i686`, and an empty or
unset value will build all artifacts.
Please note that the `mingw-w64-git` packages are built always, as it
would be tricky to figure out when they need to be built (for example,
`build_only=portable-x86_64` technically does not need `pkg-i686` to be
built, while `build_only=portable` does).

"git receive-pack" used to use all the local refs as the boundary for
checking connectivity of the data "git push" sent, but now it uses
only the refs that it advertised to the pusher. In a repository with
the .hideRefs configuration, this reduces the resources needed to
perform the check.

On my use case involving 771 islands of Linux on kernel.org,
this reduces memory usage by around 25MB. The bulk of that
comes from free_remote_islands, since free_config_regexes only
saves around 40k.
This memory is saved early in the memory-intensive pack process,
making it available for the remainder of the long process.

When serving a push, git-receive-pack(1) needs to verify that the
packfile sent by the client contains all objects that are required by
the updated references. This connectivity check works by marking all
preexisting references as uninteresting and using the new reference tips
as starting point for a graph walk.
Marking all preexisting references as uninteresting can be a problem
when it comes to performance. Git forges tend to do internal bookkeeping
to keep alive sets of objects for internal use or make them easy to find
via certain references. These references are typically hidden away from
the user so that they are neither advertised nor writeable. At GitLab,
we have one particular repository that contains a total of 7 million
references, of which 6.8 million are indeed internal references. With
the current connectivity check we are forced to load all these
references in order to mark them as uninteresting, and this alone takes
around 15 seconds to compute.
We can optimize this by only taking into account the set of visible refs
when marking objects as uninteresting. This means that we may now walk
more objects until we hit any object that is marked as uninteresting.
But it is rather unlikely that clients send objects that make large
parts of objects reachable that have previously only ever been hidden,
whereas the common case is to push incremental changes that build on top
of the visible object graph.
This provides a huge boost to performance in the mentioned repository,
where the vast majority of its refs hidden. Pushing a new commit into
this repo with `transfer.hideRefs` set up to hide 6.8 million of 7 refs
as it is configured in Gitaly leads to a 4.5-fold speedup:
Benchmark 1: main
Time (mean ± σ): 30.977 s ± 0.157 s [User: 30.226 s, System: 1.083 s]
Range (min … max): 30.796 s … 31.071 s 3 runs

Summary
'pks-connectivity-check-hide-refs' ran
4.56 ± 0.05 times faster than 'main'
As we mostly go through the same codepaths even in the case where there
are no hidden refs at all compared to the code before there is no change
in performance when no refs are hidden:
Benchmark 1: main

Users can optionally hide refs from remote users in git-upload-pack(1),
git-receive-pack(1) and others via the `transfer.hideRefs`, but there is
not an easy way to obtain the list of all visible or hidden refs right
now. We'll require just that though for a performance improvement in our
connectivity check.

The functions that handle exclusion of refs work on a single string
list. We're about to add a second mechanism for excluding refs though,
and it makes sense to reuse much of the same architecture for both kinds
of exclusion.
Introduce a new `struct ref_exclusions` that encapsulates all the logic
related to excluding refs and move the `struct string_list` that holds
all wildmatch patterns of excluded refs into it. Rename functions that
operate on this struct to match its name.
