Make the CI faster (#2475)

Without the `-fsanitize-memory-track-origins` flag, MSAN job is ~30%
faster. Since this flag is useful only while debugging (and not to
simply discover memory issues), avoid it on the CI. Note that, by
default it is still enabled by default.

Right now, MingW runs on *every* ubuntu builds: limit it only to the
standard matrix (i.e. ubuntu 20.04, 22.04, 24.04 with default
configuration), without any sanitizers (note that MingW doesn't support
*san anyway).

armhf job is by far the longest job in the CI: remove asan configuration
to make it faster. Note that we already have a lot of different jobs (on
x86_64) with some sanitizers, and that the other 2 jobs on arm/s390x don't
have asan support anyway.
If we really, really want a job with arm + asan we can add it as a
async/scheduled job.

Remove an old workaround for ubuntu jobs

Avoid installing packages needed only for the documentation

About `check_symbols.sh` script: even if uses the compiled library/objects,
it basicaly only checks if we are using, in the source code, same functions
that we shoudn't. We don't need to perform the same kind of check so
many times..
