For now, leave these jobs out during merge requests.

This makes room for future equivalents for other architectures.
The packaging jobs produce universal binaries, so leave them as-is.

Our custom build includes a patch to avoid server startup timeouts.

The upstream release includes binaries for the architectures we need.
However, the binaries do not have execute permission in their tarballs,
so add it explicitly.

It is a universal binary for both `x86_64` and `arm64` architectures.

Use `linux_release` in names associated with building or testing
release-style binaries.  Add a `.linux_package` helper to adjust
the release binary build behavior for package-specific jobs.

Avoid requiring Windows CI hosts to have WiX installed.

Invoke-WebRequest uses a progress bar by default, but we have no
interactive session anyway.  Turn it off to speed up downloads.

In order to support modern macOS features like Dark Mode, we need to use
Qt 5.15, which requires macOS 10.13.  However, we still want to support
macOS 10.10 as well, for which we need to use Qt 5.9.  Build separate
macOS packages for these use cases.

Upload binaries to `cmake.org` through its own name rather than
through the `public.kitware.com` alias.

Backport the upstream Qt patch [1] to link Qt binaries using the
`-isysroot` flag instead of `-Wl,-syslibroot`.  This is needed so that
the binaries have a SDK version set, which is needed for runtime
validation on modern macOS versions.

Update our deployment target to macOS 10.10.
This is required by Qt 5.9.

It is not compatible with building for multiple architectures.

Avoid using the macOS version running on the CI job host that happens
to run the build job.

The gmock libraries are referenced by GTest's CMake package files.

While at it, also explicitly install gettext.  It is installed already,
but make it explicit for future testing of the FindGettext module.
