Always throw TypeException on throwing zpp failures
Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to report FAILURE errors using a TypeException instead of a Warning, like it would happen in strict mode. Adds a zend_parse_parameters_throw() convenience function, which invokes zpp with this flag. Converts all cases I could identify, where we currently have throwing zpp usage in constructors and replaces them with this API. Error handling is still replaced to EH_THROW in some cases to handle other, domain-specific errors in constructors.
