This requires replacing inclusions of it with inclusions of more specific prefs files. The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h, and is used in `Codegen.py` because doing something smarter is tricky and suitable for a follow-up. As a result, any change to StaticPrefList.yaml will still trigger recompilation of all the generated DOM bindings files, but that's still a big improvement over trigger recompilation of every file that uses static prefs. Most of the changes in this commit are very boring. The only changes that are not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.
