Replace WLMP feature flag with SOP/SRP feature flags

For performance testing, more granular control is required over the Shared Offset Partitioning and Shared Result Partitioning optimizations that are part of the with-loop modulo partitioning traversal.
To achieve this control, this MR adds feature flags for SOP and SRP, while removing the feature flags for WLMP to prevent inconsistency between the three options.
