Make improvement to getParameterFromConfigV2

[dttung2905]

From the slack discussion, we should make some improvements to the getParameterFromConfigV2 util function to make it more readable.
I create a new PR instead of adding on to #5319 as I want to make this change modular, just showcasing the alternative without refactoring hundreds of lines on the other PR.
How we use the function would be something like

 getParameterFromConfigV2(
			&scalersconfig.ScalerConfig{TriggerMetadata: testData.metadata, AuthParams: testData.authParams, ResolvedEnv: testData.resolvedEnv},
			testData.parameter,
			testData.targetType,
			UseMetadata(testData.useMetadata),
			UseAuthentication(testData.useAuthentication),
			UseResolvedEnv(testData.useResolvedEnv),
			IsOptional(testData.isOptional),
			WithDefaultVal(testData.defaultVal),
		)

this is looking promising, I wouldn't necessarily make every argument to getParameterFromConfigV2 an option because some are actually required, otherwise the invocation of the function doesn't make much sense.

overall pretty good!

This is looking good, I like the direction.
