This moves most of the code to be Rust, except potentially some evaluator
functions, and allows to unblock the use case from any-hover / any-pointer and
remove nsMediaFeatures.

We match with AllLinksVisitedAndUnvisited for style invalidation, and we already
do a subtree restyle because :visited matching doesn't depend on the actual
element state.
So all this stuff is just not needed. The comment points to the attribute tests
in bug 1328509, but those still trivially pass with this change.
I think this was unneeded since I introduced AllLinksVisitedAndUnvisited, or
maybe since https://github.com/servo/servo/pull/19520. In any case it doesn't
really matter, and I already had done this cleanup in my WIP patches for
bug 1406622, but I guess this is a slightly more suitable place to land them :)

We force a repaint from ContentStateChangedInternal if visited links are
disabled, and that's observable. Let's cut it off as early as we can to avoid
timing attacks even when :visited is disabled.

Correctness improvements:
* UTF errors are handled safely per spec instead of dangerously truncating
strings.
* There are fewer converter implementations.
Performance improvements:
* The old code did exact buffer length math, which meant doing UTF math twice
on each input string (once for length calculation and another time for
conversion). Exact length math is more complicated when handling errors
properly, which the old code didn't do. The new code does UTF math on the
string content only once (when converting) but risks allocating more than
once. There are heuristics in place to lower the probability of
reallocation in cases where the double math avoidance isn't enough of a
saving to absorb an allocation and memcpy.
* Previously, in UTF-16 <-> UTF-8 conversions, an ASCII prefix was optimized
but a single non-ASCII code point pessimized the rest of the string. The
new code tries to get back on the fast ASCII path.
* UTF-16 to Latin1 conversion guarantees less about handling of out-of-range
input to eliminate an operation from the inner loop on x86/x86_64.
* When assigning to a pre-existing string, the new code tries to reuse the
old buffer instead of first releasing the old buffer and then allocating a
new one.
* When reallocating from the new code, the memcpy covers only the data that
is part of the logical length of the old string instead of memcpying the
whole capacity. (For old callers old excess memcpy behavior is preserved
due to bogus callers. See bug 1472113.)
* UTF-8 strings in XPConnect that are in the Latin1 range are passed to
SpiderMonkey as Latin1.
New features:
* Conversion between UTF-8 and Latin1 is added in order to enable faster
future interop between Rust code (or otherwise UTF-8-using code) and text
node and SpiderMonkey code that uses Latin1.

1. We will add more shape-like types in the future, so it's better to
use union to reduce the memory usage.
2. Those shape-like types are mutual exclusive, so we could use union to
wrap them.
