Currently we require -o option:parse-arguments for signatures to function properly. This makes both the signatures and the event pipeline less efficient.

As a first step, let's remove argument parsing and use the raw arguments values in signatures.
This means we should update the golang signatures to use the libbpfgo consts and remove parse-arguments from being enabled by default with the pipeline. libbpfgo already have argument parsing helpers in a separate module so they can be used as enum values in signatures.

Next steps (not part of this issue) include:

• Find a way to export libbpfgo constants to rego and cel-go Add a way to keep parsed arguments for cases where REGO signatures are wanted (Parse argument in a separate argument instead of inline #3008).
• Support event data filtering using "parsed" argument values #3019
