Font code is the only thing that was using Au in the style system without
interfacing with Gecko, and there was no real reason for it to do so.
This slightly simplifies the code.

We need to ensure the rules that override all properties for scrollbar
part elements only apply to those that are NAC (and so will be eligible
for NAC style sharing). We have some uses of non-NAC <scrollbar>
elements that should continue to inherit properties from their parents.
To avoid any changes in rule matching order that come with changing specificity,
we add a new :-moz-native-anonymous-no-specificity pseudo-class.
While we're here, we note :-moz-native-anonymous-no-specificity (and the
regular :-moz-native-anonymous pseudo-class) as not needing style
sharing cache revalidation, as we never share NAC styles.

Disable H2 ALPN.
This was introduced by #24976, and it breaks loading https://google.com. Without any network specialists currently contributing to Servo regularly, I would rather revert the particular change that broke it rather than attempt to continue investigating.
