config: enable PIPELINE_2_0 for IPC4 fuzz testing

This patch enables the PIPELINE_2_0 configuration for IPC4 fuzz testing
by updating the fuzz_IPC4_features.conf file. The PIPELINE_2_0 flag is
required for certain new features, such as DP_SCHEDULER, and improves
code coverage for the IPC4 configuration.

This option is enabled on all platforms using IPC4, with the exception
of those based on CAVS, which are not used in production. The change has
been tested locally and does not introduce any regressions.
