gs-effect: Add HasParameter and fix Set*Array
HasParameter can be used to safely check if a parameter exists and such should be preferred over try-catch blocks. Additionally, SetFloat2, SetFloat3, SetFloat4, SetFloatArray, SetInteger2, SetInteger3, SetInteger4 and SetIntegerArray should no longer cause rendering issues due to invalid buffer sizes.
