Subject: [PATCH] geckolib: Update bindings with vtable generation and
 anonymous unions

Only 9 tests failing!

```
bindgen_test_layout_FontFamilyList
bindgen_test_layout_StyleAnimation
bindgen_test_layout_nsFont
bindgen_test_layout_nsStyleBackground
bindgen_test_layout_nsStyleDisplay
bindgen_test_layout_nsStyleFont
bindgen_test_layout_nsStyleGridTemplate
bindgen_test_layout_nsStylePosition
bindgen_test_layout_nsStyleSVG
```

The dependencies are:

 * FontFamilyList makes nsFont fail which makes nsStyleFont fail.
 * nsStyleGridTemplate makes nsStylePosition fail
 * StyleAnimation makes nsStyleDisplay fail

nsStyleGridTemplate and nsStyleSVG failures seem to be bitfield-related.

Except the bitfield-related values and those deps, I don't know what
might cause the other failures, we'll have to check carefully C++
member alignments.
