IDL: Drop redundant null check for string and wrapper type attributes
For nullable string and wrapper type attributes, we use a null string or
null pointer return value from the C++ getter to represent a null
Javascript value.
Rather than generating a separate null check and v8SetReturnValueNull()
call for these types, we can use v8SetReturnValueStringOrNull() for
strings, and for wrapper types, we can always use the per-type
v8SetReturnValue() overload, since they convert null pointers to null
Javascript values already.
