feat: add proc label to issues

[amd-aliem]

Addressing #218: Add proc-XxxX labels for processor generation.

New module added - proc-model, which has a new script that can return the host machine's codename (i.e. Genoa/Milan), or its series (i.e. 7004, 9005).

example issue created during test: amd-aliem#75

example: amd-aliem#75 with label proc-7xx3

Currently parsing /proc/cpuinfo, potentially can move to using another tool or python script for a more direct approach

For this one, there’s one point I’d like to discuss first. It may make sense to move the processor-type discovery outside of Beacon-Report.

The reasoning is that this information will be used for more than just populating issues. It will also be needed to gate or “unblock” processor-specific tests as those are added, and to report the processor model in the generated certificates.

Given those additional use cases, it might be better to adjust the processor discovery logic here so it’s more forward-looking and reusable across the project.

@DGonzalezVillal ready for re-review! Created new module w/ the python snippet you gave me extended. Added a series command for the 9005 version, and a codename command for Genoa/Milan etc.
