ISA Levels: Add /proc/cpuinfo files for different CPUs and set up test cases

[ermo]

It is probably wise to build a high degree of confidence via tests, as correct /proc/cpuinfo parsing of the ISA levels of different CPUs lie at the core of our Smart System Management promises re. auto-installing faster binaries on systems that support it.

• Consider adding an optional file argument that defaults to /proc/cpuinfo for ease of testing different /proc/cpuinfo files from various systems. (added in https://github.com/serpent-os/moss-core/commit/d4549e1d474e3cc11073bbe652475831cfa0f4f7 and https://github.com/serpent-os/moss-core/commit/23cf643c803e520a3c98578fca0396c2aaed91bd)

Suggested test cases:

AMD:

• AMD Phenom II (1090T) (should be -v1)
• AMD Piledriver (FX-8350) (should be -v2)
• AMD (... other Bulldozer-derived generations ...)
• AMD Zen (R7 1700) (should be be -v3x)
• AMD Zen+ (R7 2700X) (should be -v3x)
• AMD Zen2 (R9 3900X) (should be -v3x)
• AMD Zen3 (R9 5900X) (should be -v3x)
• AMD Zen4 (R7 7700X) (should be -v3x)

Intel:

• Intel Yorkfield (Q9400) (should be -v1)
• Intel Atom (?) (should all be -v2)
• Intel Nehalem (?) (should be -v2)
• Intel Westmere (?) (should be -v2)
• Intel Sandy Bridge (ix-2xxx) (should be -v2)
• Intel Ivy Bridge (ix-3xxx) (should be -v2)
• Intel Haswell (ix-4xxx) (should be -v3x)
• Intel Broadwell (ix-5xxx) (should be -v3x)
• Intel Skylake (ix-6xxx) (should be -v3x)
• Intel Core 7th gen (should be -v3x)
• Intel Core 8th gen (should be -v3x)
• Intel Core 9th gen (should be -v3x)
• Intel Core 10th gen (should be -v3x)
• Intel Core 11th gen (should be -v3x)
• Intel Core 12th gen (should be -v3x)
• Intel Core 13th gen (should be -v3x)

Hi. I have AMD 2700X (Zen+) Do you want a textfile with the info from /proc/cpuinfo?

If you could do a PR where you add it as a text file and add the corresponding test case yourself, that'd be preferred?

It should be pretty self-evident how to do it if you look at e.g. https://github.com/serpent-os/moss-core/commit/474f2a4ee344ff2e0aacb79f765075cbf53b4f8c

I created a PR now... I hope that i did it right as it is along time since i did a PR.
