- bump rest of the workflows (windows, macos, distrocheck).
- non-native virtualized envs have 2 CPUs, bump down accordingly.
(for `vmactions/omnios-vm` it's just a guess.)
- bump all to nproc + 1.

To test without c-ares and hit `easy_lock.h` on an old system. Use this
new build step to introduce small variations, and also test libssh2.
Also add workaround to existing job to enable libssh. (CMake's generic
auto-detection doesn't seem to work here.):
```
CMake Warning at CMakeLists.txt:908 (find_package):
Could not find a package configuration file provided by "libssh" with any
of the following names:
libsshConfig.cmake
libssh-config.cmake
```

- cmake: fix `-pedantic-errors` for old CMake with `CURL_WERROR=ON` set.
`-pedantic-errors` option throws a warning with GCC (all versions) and
makes `check_symbol_exists()` fail in CMake versions older than
v3.23.0 (2022-03-29), when CMake introduced a workaround:

- set `CURL_WERROR=ON` for the `linux-old` job in CI.
Closes#13282
Unity mode is not supported by CMake v3.7.2 used in linux-old, but
enable it anyway for consistency and to kick in automatically once
migrating to a newer old Linux in the future.
Also:
- replace `CMAKE_COMPILE_WARNING_AS_ERROR` with `CURL_WERROR`.
- delete default build option `PICKY_COMPILER=ON`.
Closes#13277
This version still has ELTS support and contains some old versions of
key components like cmake to help prevent us from breaking that support.
Closes#13029
