Drop CSS cursor quirk for missing fallback cursor.

Drop CSS cursor quirk for missing fallback cursor.

IE used to allow URI cursors without a specified pre-defined cursor value
fallback. This CL removes the support for that quirk because IE allegedly
dropped this quirk in IE9, even in the compat modes (see issue 286668).

Made the existing parsing tests run in strict mode and moved test cases for
quirks mode to a new file.

The 'hand' -> 'pointer' quirk was not touched.
