drivers/perf: arm_pmu: add common attr group fields
In preparation for adding common attribute groups, add an array of attribute group pointers to arm_pmu, which will be used if the backend hasn't already set pmu::attr_groups. Subsequent patches will move backends over to using these, before adding common fields.
