Similar to the fix in openjdk17.

For more information and lessons learned see ports commit
fa96c62b2e3cacce280053fda46dedd8b84a1018 and the follow-up commits.

Implement getCommittedVirtualMemorySize() directly using sysctl
kern.proc.vmmap
Implement getOpenFileDescriptorCount() directly using sysctl
kern.proc.nfds

Note on openjdk17 use closefrom where possible (note this use case is
only in openjdk 17, 21, 23 and 24)

Remove the message about the use of fdescfs(5) as this is not needed
for sure, keep the information about procfs(5) as I have not analysed
enough the source code to make sure it is not used anywhere else, but
I don't think it is.

Printf was confused because the argument was used as format string
and contained a %.
The issue is only cosmetical so not bumping port revision.

It is mentioned in the PR that an upstream fix is in openjdk25.

OpenJDK installation inform that fdescfs(5) and procfs(5) should be
mounted when using OpenJDK.
After doing some test and some traces, it seems that this should be
no so usefull, some applications will require it, but most of java
applications doesn't seems to suffer to work or performance when
such pseudo FS is not mounted.

So this change request permit to let local administrator to decide if
it is really needed or not.

Generally disable warnings-as-errors for all openjdk ports, removing all
the conditionals we have now for particular architectures and/or
compilers. It does not make sense to have this on by default, unless you
are an upstream maintainer.
