net-dns/knot-resolver: add 6.0.9

Knot DNS API/ABI : >=net-dns/knot-3.3

New optional python component, manager, to start/manage Knot Resolver :
* useflag manager (enabled by default)
* python3_10..12 (no 3.13 due to app-admin/supervisor)
* start with /etc/init.d/knot-resolver or knot-resolver.service
* config file : /etc/conf.d/knot-resolver /etc/knot-resolver/config.yaml
* option garbage collector : /etc/init.d/kres-cache-gc

Old/legacy way to start Knot Resolver is still supported and installed by default, even with the manager enabled by useflag :
* start with /etc/init.d/kresd or kresd'@'.service (installed by default with the meson_feature systemd_legacy_units)
* config file : /etc/conf.d/kresd /etc/kresd.conf (installed by default with -Dinstall_kresd_conf=enabled)

Useflags :
* kresc (removed) : has never gone beyond experiment/alpha
* prometheus (new) : prometheus metrics endpoint for the manager (dev-python/prometheus-client)

Patches :
* 5.X patches to set docdir and optional deps (nghttp, openssl)
* 6.0.9-libsystemd.patch : rebase from 5.7.4. tmpfiles is independent of the systemd option/useflag
* 6.0.9-config-example.patch : for the manager. A default config file is installed in /etc/knot-resolver/config.yaml and examples in /usr/share/doc/
* 6.0.9-sd_notify_alt.patch : upstream, fix systemd dep with sd_notify alternative for manager
* 6.0.9-pytest_tomli.patch : for one pytest, import toml is replaced with tomli

Tests :
* unit_tests for kresd : enabled
* unit_tests for manager : enabled
* config_tests : disabled. It requires external lua modules (basexx, cqueues)
* extra_tests : disabled. Too extra ...
