Bug 1415805 - throw exception at region.lines setter if value is negative.

https://reviewboard.mozilla.org/r/200208/#review205396

There is no wpt test for this?

Bug 1415805 - region.scroll setter should not throw.

https://reviewboard.mozilla.org/r/200210/#review205404

It should throw, but not from the method, but automatically from the bindings layer https://heycam.github.io/webidl/#es-enumeration.
We aren't following the spec here since we use DOMString and not ScrollSetting.
Is there any reason to not follow the spec?

We have wpt test, and enable them in other patch/commit.

Why we need the if check. Just always assign the value.
The generated endguard value shouldn't be used

https://www.w3.org/TR/webvtt1/#dom-vttregion-scroll
The value of scroll can only be "up" or "", and there is also wpt test to test them.

https://www.w3.org/TR/webvtt1/#dom-scrollsetting
The _empty is the empty string, not the guard value.

The generated code in VTTRegionBinding.cpp :
extern const EnumEntry strings[3] = {
  {"", 0},
  {"up", 2},
  { nullptr, 0 }
};

Or did I miss something in the webidl file?
