RFR: 8313306: More sensible memory reservation logging [v14]

[Sonia Zaldana Calles]

> This PR implements more specialized logs for virtual memory APIs in the “os” namespace. It uses “os” and “map” as log tags using unified JVM logging as introduced in JEP 158 (https://openjdk.org/jeps/158). 
> 
> As far as testing is concerned, I have added a regression test to verify the logging is working accordingly.
