Fix some Non-Contiguous CBM capability detection issues on Intel, AMD and Hygon platforms

Description

Fix three issues of L3/L2 cache Non-Contiguous CBM capability detection on Intel, AMD and Hygon platforms: (1) lib: Fix L3 cache Non-Contiguous CBM capability with MSR interface for AMD and Hygon (for AMD and Hygon) (2) lib: Add L3 cache Non-Contiguous CBM capability detection with OS interface (for Intel, AMD, and Hygon) (3) lib: Add L2 cache Non-Contiguous CBM capability detection with OS interface (for Intel)

Affected parts

• [x] library
• [ ] pqos utility
• [ ] rdtset utility
• [ ] other: (please specify)

Motivation and Context

Fix three issues of L3/L2 cache Non-Contiguous CBM capability detection on Intel, AMD and Hygon platforms. Detect and display the correct L3/L2 cache Non-Contiguous CBM capabilities.

How Has This Been Tested?

(1) Passed "pqos -d" test:

$ pqos --iface msr -d | grep "Non-Contiguous CBM"
                Non-Contiguous CBM: unsupported/supported

$ pqos --iface os -d | grep "Non-Contiguous CBM"
                Non-Contiguous CBM: unsupported/supported

(2) Passed all tests in intel-cmt-cat/unit-test.
