Caught by the clang static analyzer.

* UIProcess/API/Cocoa/WKProcessPool.mm:
(policiesHashMapToDictionary): Switch from using
[[NSMutableDictionary alloc] init] which returns a +1 retained
object in MRR to [NSMutableDictionary new] which returns an
autoreleased object under MRR.  This bug caused 3 leaks when
calling -[WKProcessPool _pluginLoadClientPolicies], which should
return an autoreleased object based on its signature.
