MINOR: Reduce duplicate parameter combinations in heavy Streams integration tests (#22125)

Cuts redundant parameterized cases from three slow Streams integration
tests without losing meaningful coverage:

  - IQv2StoreIntegrationTest — skips withHeaders=true rows for kind=PAPI
and for global stores. DSL_STORE_FORMAT_CONFIG (the setting withHeaders
toggles) only affects DSL stores built without an explicit supplier,  so
those rows are exact duplicates of the withHeaders=false runs.
