[PATCH v4 1/3] common/qat: isolate parser arguments configuration

[Arkadiusz Kusztal <arkadiuszx.kusztal@intel.com>]

This commit isolates qat device arguments from the common
code. Now arguments are defined per service, and only appear
in the application if the service is compiled-in.

Depends-on: patch-137466 ("common/qat: add virtual qat device (vQAT)")

Signed-off-by: Arkadiusz Kusztal <arkadiuszx.kusztal@intel.com>
---
v2:
- added pmd isolation
v3:
- added fix for legacy flag
v4:
- fixed an issue with devargs segfault
