[PATCH pve-qemu] parse-cpu-flags: stop filtering out 'pmu'

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

'pmu' was excluded from the list of flags in the custom CPU flag dialog
because it is not a CPUID flag (not part of '-cpu help' output).
However, it is a plain boolean property so it fits the [+-]<flag> syntax
from the custom CPU config, and QEMU accepts it when set manually via
'+pmu'.

Windows guests using VBS need a virtual PMU, which is not enabled by
default on many models (EPYC-Turin, EPYC-Genoa, SapphireRapids, and
presumably others I have not tested). This currently requires users to
edit the config by hand since the flag cannot be selected in the UI.

Remove 'pmu' from the blacklist so it shows up in the generated flag
list.
