In gen/sku specific tests include only required files to reduce
dependency on not related HW scpecific headers and improve build
performance.
This is achieved by reduce in usage of hw_test.h and related collateral,
like shared/source/helpers/definitions/hw_cmds.h which can be replaced
by sku specific hw_cmds_<sku>.h
