feat(kics): add usage of parallel flag for analyzer

[pereiramarco011]

Closes #6934

Proposed Changes

• Use the already added parallel flag to set the number of workers on the analyze portion of the scan command
• Use the already added parallel flag to set the number of workers on the analyze standalone command
• Add unit test for flag adjust value utils func

Hi, thanks a bunch for this contribution! Should help solve my issue (#6934).

I have a quick question that maybe I'm misunderstanding:
This solution uses the same amount of parallel workers for both scan and analyze when running kics scan, correct?
So the behavior is the following - setting X parallel workers in the scan flags will scan using X * platforms workers, while the analyze section will only run X parallel workers.
Hypothetically, if KICS supported 100 platforms and one wants a maximum of 100 concurrent workers, one would set the parallel flag to 1 and then analyze would run with a single worker (and unavoidably so).

Is this the intended behavior?
