crypto: qat - consolidate service enums

The enums `adf_base_services` (used in rate limiting) and `adf_services`
define the same values, resulting in code duplication.

To improve consistency across the QAT driver: (1) rename `adf_services`
to `adf_base_services` in adf_cfg_services.c to better reflect its role
in defining core services (those with dedicated accelerators),
(2) introduce a new `adf_extended_services` enum starting from
`SVC_BASE_COUNT`, and move `SVC_DCC` into it, as it represents an
extended service (DC with chaining), and (3) remove the redundant
`adf_base_services` enum from the rate limiting implementation.

This does not introduce any functional change.
