[v5,0/6] KVM: selftests: Improve PMU event filter settings and add test cases

Message

Hi,

This patch series aims to improve the PMU event filter settings with a cleaner
and more organized structure and adds several test cases related to PMU event
filters.

These changes help to ensure that KVM's PMU event filter functions as expected
in all supported use cases.

Any feedback or suggestions are greatly appreciated.

Sincerely,
Jinrong Liang

Changes log:

v5:
- Add more x86 properties for Intel PMU;
- Designated initializer instead of overwrite all members; (Isaku Yamahata)
- PMU event filter invalid flag modified to "KVM_PMU_EVENT_FLAGS_VALID_MASK << 1"; (Isaku Yamahata)
- sizeof(bitmap) is modified to "sizeof(bitmap) * 8" to represent the number of
  bits that can be represented by the bitmap variable. (Isaku Yamahata)
