Add VyOSElasticModernHost + placeholder engine stub

Host class mirrors PhabricatorElasticsearchHost's surface. Engine is
a stub providing only getEngineIdentifier() and getHostType() so the
host's tests can construct an engine instance; real engine
implementation lands in subsequent commits. All six abstract methods
of PhabricatorFulltextStorageEngine are implemented (four as throwing
stubs to be replaced in E7/E8).

.arcconfig gains "src/" in the load list so arc unit can discover the
extension library; test case extends PhutilTestCase (no DB needed for
pure-PHP host property assertions).
