[SOLR-12385] Tests extending SolrTestCaseHS should be cut over to SolrCloudTestCase, and unique SolrTestCaseHS functionality should be folded into the standard test infrastructure

Description

SolrTestCaseHS is extended only by JSON facet and JSON request tests.

SolrTestCaseHS was introduced with JSON faceting in SOLR-7214 (I believe "HS" is short for HelioSearch, where the functionality was originally developed). It appears to enable a primitive distributed functionality, with no ZooKeeper, allowing tight control of document distribution, like SolrCloud's implicit routing.  Some JSON-specific handling stuff in there too, which I think could be relocated to JSONTestUtil.

Alan Woodward and others did a bunch of test conversions to SolrCloudTestCase (e.g. SOLR-9132, SOLR-9110, SOLR-9065), but AFAICT never mentioned SolrTestCaseHS-based tests as a target.
