Bug 163429 – [Web IDL] Update [CachedAttribute]'s behavior now that we support [SameObject]

• Component: Bindings
• Status: ASSIGNED

[Chris Dumez]

[SameObject] and [CachedAttribute] currently mean the same thing, so to clean things up:
- Rename [CachedAttribute] to [SameObject] in all IDLs where we always return the same object.
- Update [CachedAttribute] to ask the implementation since if the value has changed since the last access before actually using the cached value. This allows for caching attributes but adds flexibility by supporting invalidation. This is used now used by History.state instead of using custom bindings code to achieve this. In a follow-up patch, this will also be used for MessageEvent.data to fix a bug. I am also considering making [CachedAttribute] being the implicit default for FrozenArray attributes to match the specification more closely.
