Reviewed by Chris Fleizach.

AccessibilityObjectInclusion only has three variants, so it can be sized as a uint8_t. Right now it's sized as the
default type for enum class, int, which is 4 bytes.

This saves 1.7mb on http://html.spec.whatwg.org when using VoiceOver (567769 AccessibilityObjects * 3 bytes saved each).
