Allow site specific archive settings

[Starker3]

In #18279 an option was added to disable archiving for segments and the option also allows it to be disabled for specific Site IDs the same way that it works for tracker settings (Eg. [General_{siteId}])

It would be quite useful if this also worked for some other [General] config settings as well, specifically like the datatable_archiving_maximum_rows settings listed in this FAQ: https://matomo.org/faq/how-to/faq_54/

For users that have a lot of sites on one instance or even with a few sites where some might be high traffic, it would enable users to have site specific row limits without needing to change the setting for all sites on that instance.

Just a general note on the effort that is needed to make that possible:
In almost all cases we are currently using Config::getInstance()->General['someconfig'] to access config values.
With #18279 we introduced the class GeneralConfig, which automatically tries to use a site specific config if available.
So it's basically "only" replacing Config::getInstance()->General['someconfig'], with GeneralConfig::getConfigValue('someconfig', $idSite). But this will actually only work smoothless in places where the siteid is already available or can be easily fetched.

This issue has been mentioned on Matomo forums. There might be relevant details there:

This would be great or just maybe to use different config.ini.php in matomo-archive cron (--force-idsites --force-config)?

TNX!

We have another request for this today from a user.

In this users case they want to be able to use the Unique Visitor metrics for things such as Year or Date Range, but if they enable it on their instance it cripples their DB because it also enables it for their high traffic sites. Having this only enabled for a low traffic site would help them greatly.

We have another request for this feature from a customer today, having the unique visitor metric is only necessary for some small sites but in order to use it they have to enable it for all sites which causes the archiving to slow to a crawl.
