[PATCH manager v3] api/pvestatd: broadcast and expose non-x86 host architecture

[Dominik Csapak <d.csapak@proxmox.com>]

in case a nodes runs a non-x86 kernel, broadcast that info into the
'static-info' hash to pmxcfs (once). Use that info to add an
'architecture' property to /cluster/resources.

x86 nodes won't return a value here.

changes from v2:
* use Tools get_host_arch instead of POSIX::uname()
* fix adding the arch only when it's non-x86
* rename variable and api property to 'host-arch'

sending only the api patch for a v3 for now

just to note, the only ui adaptations for this needed are in
[05/17] ui: qemu: add architecture specific defaults and helpers

namely the two occurences of:
PVE.data.ResourceStore.getNodeById(nodename)?.data.architecture;

need a change to
PVE.data.ResourceStore.getNodeById(nodename)?.data['host-arch'];
