Adds JsonParserCall which models a call to a JSON parser.

  • I've deprecated the AST-based JsonParseCall to avoid confusion.
  • The default taint step through JSON.parse has been updated to include JsonParserCall.
  • The NosqlInjection query used two-pass taint tracking to identify user-controlled JSON.parse calls, and then use those as sources. This was redundant with the taint step through JSON.parse, however. This has been removed, instead relying on the standard taint step. I've added a test to make sure it still works. In theory, some results may disappear since the two-step solution technically allowed for mismatched call/returns.
