IVGCVSW-2503 Refactor RefElementwiseWorkload around Equal and Greater

	* Remove Equal and Greater from RefElementwiseWorkload
	* Create RefComparisonWorkload and add Equal and Greater
	* Update ElementwiseFunction for different input/output types
	* Update TfParser to create Equal/Greater with Boolean output
	* Update relevant tests to check for Boolean comparison
