[libvirt] [PATCH] docs: Break up 'Basic Resources' XML section



We had a bit too many elements crammed in there. Separate it into different
headings:

- CPU Allocation (<vcpus>)
- CPU Tuning (<cputune>)
- Memory allocation (<memory> and <currentMemory>)
- Memory backing (<memoryBacking>)
- Memory tuning (<memtune>)
- Numa tuning (<numatune>)
- Block I/O tuning (<blkiotune>)
