crypto: qat - add decompression service for rate limiting

Add a new base service type ADF_SVC_DECOMP to the QAT rate limiting (RL)
infrastructure. This enables RL support for the decompression (DECOMP)
service type, allowing service-level agreements (SLAs) to be enforced
when decompression is configured.

The new service is exposed in the sysfs RL service list for visibility.
Note that this support is applicable only to devices that provide the
decompression service, such as QAT GEN6 devices.
