This change adds `-Wno-unused-command-line-argument`
to the Clang builds since Bazel is now providing an unused
`-c` to rules that do header syntax checking only.
Rules that were missing copts which causes them to
encounter this error are also fixed.

annotations in string_view with an upgraded Clang.
It is also no longer necessary to uninstall google-benchmark

`MODULE.bazel` is now the recommended way to use Bazel.
Users that have wanted to use `WORKSPACE.bazel` still needed
to provide their own `WORKSPACE.bazel` file, so this file
provides no benefit to them. It was merely for us to test,
but there is little reason to do so.
Support for `WORKSPACE.bazel` is going away in Bazel 9.

According to
https://github.com/google/oss-policies-info/blob/main/foundational-cxx-support-matrix.md
the GCC7 is supported, but since it lacks complete C++17 support, we
can ignore it. GCC8 is only supported by openSUSE/Leap and contains a
pretty bad bug for us, so for it is best to test GCC9 instead.

Linux "latest" containers updated to
GCC 14.2
CMake 3.31.2
Bazel 8.0.0
Included are various fixes to get these versions to work.
Bazel now references repositories by their canonical names from the
Bazel Central Registry. For example, Abseil is now @abseil-cpp instead
of @com_google_absl, and GoogleTest is now @googletest instead of
@com_google_googletest. Users still using the old WORKSPACE system may
need to use `repo_mapping` on repositories using the old names. See
`WORKSPACE.bazel` in this commit for an example.

When bzlmod is enabled and WORKSPACE.bzlmod exists, the content of
WORKSPACE is ignored. This prevents bzlmod builds from unintentionally
depending on the WORKSPACE file.
This exposed some small problems with our clang-cl configuration,
which are also fixed in this change.

https://bazel.build/external/overview#bzlmod
Bzlmod will be the default in a future Bazel release.
By default it requires projects to be registered with the
Bazel Central Registry (https://registry.bazel.build/) and
thus uses regular releases by default.
Users that want to "live-at-head" can still do this through
with overrides (https://bazel.build/external/module#overrides).
This change updates Abseil dependencies to use released versions.
CI uses Bzlmod except in the case of linux_gcc-floor, which will
keep testing the old WORKSPACE-based dependency system.

This makes them interchangeable in contexts known to be compiled as C++20.
This also makes `absl::` ordering types compatible with `<=>`, allowing to
unconditionally use `absl::` spelling for types but conditionally use `<=>`
