tools/xenstore: add memory accounting for nodes

Add the memory accounting for Xenstore nodes. In order to make this
not too complicated allow for some sloppiness when writing nodes. Any
hard quota violation will result in no further requests to be accepted.

This is part of XSA-326 / CVE-2022-42315.
