T7423: Add kernel boot options isolcpus, hugepages, numa_balancing
Add kernel options which apply during the boot:
- isolcpus
- nohz_full
- rcu_nocbs
- default_hugepagesz
- hugepages
- hugepagesz
- numa_balancing
- hpet
- mce
- nosoftlockup
- nmi_watchdog
CLI:
```
set system option kernel cpu disable-nmi-watchdog
set system option kernel cpu isolate-cpus '1,2,4-5'
set system option kernel cpu nohz-full '1,2,4-5'
set system option kernel cpu rcu-no-cbs '1,2,4-5'
set system option kernel disable-hpet
set system option kernel disable-mce
set system option kernel disable-softlockup
set system option kernel memory default-hugepage-size '2M'
set system option kernel memory disable-numa-balancing
set system option kernel memory hugepage-size 1G hugepage-count '2'
set system option kernel memory hugepage-size 2M hugepage-count '512'
```
