Get rid of outdated getter / setter raises from Web IDL

Get rid of outdated getter / setter raises from Web IDL
https://bugs.webkit.org/show_bug.cgi?id=117346

Reviewed by Darin Adler.

Stop using "getter / setter raises" in the IDL as this is no longer part of
the Web IDL specification. Web IDL no longer specifies exceptions for
attribute getters or setters. Instead, it is now explained in prose.

WebKit still needs to know if the getter / setter can throw an exception
(but does not need the exception name) so this patch adds 2 WebKit specific
IDL extended attributes: [GetterRaisesException] / [SetterRaisesException].
The naming is consistent with Blink.

This results in more standard and concise IDL. This also simplifies a lot
the code of the IDL parser.

Note that this patch does not remove "raises()" from the IDL methods yet.
This should be replaced by [RaisesException] IDL extended attribute in a
later patch.

No new tests, no behavior change.
