[webapi][TC-602] Remove test suite for W3C CSS Filter

https://bugs.tizen.org/jira/browse/TC-602 is closed as Won't Fix
So it is not a Tizen IVI specific feature any more.
[webapi] Fix screen orientation test cases according to spec.

1, We need to use a valid functionn to wrap the "fake" function callback (e.g. unreached_func() in this case).
2, According to screen orientation w3c spec http://www.w3.org/TR/screen-orientation/#orientationlocktype-enum, the "OrientationLockType" cannot be angle value such as "0", "90", "180", "270"
3, The screen.orientation.lock() cannot be invoked in parallel. That might cause the JavaScript Promise object's resolved callback not be invoked. Instead, we should call them in sequence.
