This uses Shadow DOM slotting instead of XBL, and migrates styles from
using XBL anonymous traversal to using CSS Shadow Parts.
This also removes the basecontrol binding, since this was the last
binding to extend it.

As of this change, instances of xul <button> use a custom element.
The button-base xbl binding remains for now, since it is still used
by toolbarbutton, it will be removed soon.

Otherwise we can end up setting the proper attribute on removed children when elements get disconnected
and reconnected.

The existing implementation of inherited attributes keeps a data
structure in a property on the class, but derived classes were
unintentionally getting that structure from their parent class,
preventing derived classes from declaring a different set of inherited
attributes.

This provides a flipped data structure based on the provided inheritedAttributes,
which looks like:
Object<selector, attrs_to_inherit_comma_separated>
To one that looks like:
Object<attr, Array<Array<selector, attr_to_inherit>>
This should improve performance because:
1) We only fetch element at connectedCallback that actually will have attributes inherited.
2) When an attribute changes we can quickly inherit only that one.

If MOZ_INSTRUMENT_CUSTOM_ELEMENTS is set in the environment, then modify Custom Elements
to wrap each function and property lookup to keep a count and running time. Then print out
tables for each element at startup. Tables can be re-printed with `MozElements.printInstrumentation()`.

For now, only add the MozMenuPopup base class to MozElements,
and don't define a custom element for it with
`customElements.define`. This is to help avoid conflicts in
de-xbl work. (See the bug for details.)
Includes a function to do 'manual slotting', moving child
elements into place. Dynamically adding, modifying, or
removing child nodes after the element is connected needs
to be handled manually as well.

This allows elements to skip explicitly declaring `observedAttributes` and then imperatively
calling `inheritAttribute` on the appropriate child nodes. For simple cases this means less
boilerplate and moving this logic into the base class.
This is an opt-in feature, so more complex cases can continue to manually implement inheriting
behavior as before.

Move functionality out of XULDocument::AddElementToDocumentPost:
1) Convert all XUL link elements into HTML link elements which have
code to handle when they are added to the DOM.
2) Move handling of the end of a linkset element into nsXULElement's DoneAddingChildren callback.
3) Move document direction reset to where the root element is created.
