NetBSD CI is disabled because it is not yet supported in
zig-bootstrap. Once NetBSD has proper zig-bootstrap support, it can be
re-enabled.
Windows is not solved here yet; will be pushing a separate commit for
that.
* remove unused download page html. It's now handled in the
www.ziglang.org website repo.
* add netbsd to the downloads index.json file that we send to
the www.ziglang.org website repo.
* shallow clone the website repo to avoid downloading old copies of
data.js unnecessarily.
* no longer depend on apt.llvm.org, instead we rely on a zig-bootstrap
tarball with pre-built Zig, LLVM, LLD, and Clang. Similar to the
Windows Dev Kit but for Linux. This also makes the script no longer
depend on Docker, libxml2, or GCC.
* remove bash retry logic; it was only needed for flaky apt.llvm.org
and isn't needed for the other resources we download.
* build and upload the experimental std lib automatically generated
docs. langref.html is moved to docs/langref.html because the std lib
docs are in docs/std/.
* the superfluous "zig" directory in $prefix/lib/zig/std/std.zig is
removed from the tarball.
* update_download_page makes a commit in the www.ziglang.org repository
updating data/releases.json so that repository can manage deploys.
git describe is used for version string creation, but it had to be
reverted in commit 69da6ba because it was broken in CI builds.
Azure Pipelines and Drone perform shallow clones by default.
This change reconfigures them to fetch history and tags. It adds tens of
seconds, which is negligible compared to overall build and test time.

This reverts commit c0c9303bd63468afe146ad729cf963ee06a1777f.
Thanks to commit c08444b33ff49981cd0a39cced479e2197dc4fd7 we can now
re-enable FreeBSD in the CI.
