Much like we optimize to_ascii_lowercase.
This also fixes a bug in Servo where attr() rules with an unknown namespace
prefix are parsed, which is wrong.
This is in preparation of a cascade optimization for custom properties.
This fixes various fishiness around our StyleBuilder stuff. In particular,
StyleBuilder::for_derived_style (renamed to for_animation) is only used to
compute specified values, and thus doesn't need to know about rules, visited
style, or other things like that.
The flag propagation that was done in StyleAdjuster is now done in StyleBuilder,
since we know beforehand which ones are always inherited, and it simplified the
callers and the StyleAdjuster code. It also fixed some fishiness wrt which flags
were propagated to anon boxes and text.
The text-decoration-lines bit is interesting, because the way it was implemented
in #17722 meant that display: contents elements did get HAS_DECORATION_LINES
flags only if its parent also had it, so in practice the Contents check
preserves behavior, but it's only an optimization looking at Gecko's call-sites,
so we can remove it too.

This more concrete wrapper type can write a prefix the very first time something
is written to it. This allows removing plenty of useless monomorphisations caused
by the former W/SequenceWriter<W> pair of types.
style: Move -moz-context-properties outside of mako.

style: Move text-align outside of the mako file.
I will need this refactoring before my next job. I didn't actually fix the FIXME's along the way. My other PR probably will cover these.
