registered_mutation_observers() returns immutable references and does
not init mutation observers.
registered_mutation_observers_mut() lazily initializes raredata if it
does not exist.
Updated code that uses this methods to call appropriate method when
mutation is not necessary.

Fix `#[webidl_must_inherit]` building when cwd is not servo crate root
Manifest dir should be more stable than current dir.
<!-- Please describe your changes on the following line: -->
I was trying to embed servo.
The directory layout of mine was the following:
```
/
*-servo
*-src
*-Cargo.toml
...
```
When I tried to build, cargo reported an error, in `#[webidl_must_inherit]` (Os error: 2).
After some research I have found that it failed to find `.webidl` files, because it used a path relative to `current_dir`.
I replaced current dir with manifest dir to make it more reliable.

I think this is a good change regardless of other discussion in bug 1552587. If
we decide to move `mColor` to the top-level of the struct that can be done
separately.

I need to profile this a bit more, but talos was pretty happy about this, and it
solves the known performance issues here such as the test-case from bug 1483963
for example. This also gets rid of a bunch of unsafe code which is nice.
This still keeps the same GC scheme, removing the key from the hashmap when
needed. I kept those as release assertions, but should probably be turned into
debug-only assertions.

We cannot compile with just feature(gecko + debug_assertions), since that's how
debug rusttests get compiled and they don't have the refcount logging stuff.
We were getting away with it for the pre-existing usage of the style crate,
because it wasn't used during any test and presumably the linker didn't
complain. But servo_arc is definitely used in tests.

This doesn't clean up as much as a whole, but it's a step in the right
direction. In particular, it allows us to start using simple bindings for:
* Filters
* Shapes and images, almost. Need to:
* Get rid of the complex -moz- gradient parsing (let
layout.css.simple-moz-gradient.enabled get to release).
* Counters, almost. Need to:
* Share the Attr representation with Gecko, by not using Option<>.
* Just another variant should be enough (ContentItem::{Attr,Prefixedattr},
maybe).
Which in turn allows us to remove a whole lot of bindings in followups to this.
The setup changes a bit. This also removes the double pointer I complained about
while reviewing the shared UA sheet patches. The old setup is:
```
SpecifiedUrl
* CssUrl
* Arc<CssUrlData>
* String
* UrlExtraData
* UrlValueSource
* Arc<CssUrlData>
* load id
* resolved uri
* CORS mode.
* ...
```
The new one removes the double reference to the url data via URLValue, and looks
like:
```
SpecifiedUrl
* CssUrl
* Arc<CssUrlData>
* String
* UrlExtraData
* CorsMode
* LoadData
* load id
* resolved URI
```
The LoadData is the only mutable bit that C++ can change, and is not used from
Rust. Ideally, in the future, we could just use rust-url to resolve the URL
after parsing or something, and make it all immutable. Maybe.
I've verified that this approach still works with the UA sheet patches (via the
LoadDataSource::Lazy).
The reordering of mWillChange is to avoid nsStyleDisplay from going over the
size limit. We want to split it up anyway in bug 1552587, but mBinding gains a
tag member, which means that we were having a bit of extra padding.
One thing I want to explore is to see if we can abuse rustc's non-zero
optimizations to predict the layout from C++, but that's something to explore at
some other point in time and with a lot of care and help from Michael (who sits
next to me and works on rustc ;)).

This should be an idempotent patch. The way to come up with this patch has been:
* Run the first script attached to the bug and pipe it to xclip, then paste it
in color.rs
* Add the relevant #[derive] annotations and remove the color.mako.rs
definition.
* Reorder the values to match the ColorID definition, on which some widget
prefs and caching stuff relies on.
* Manually port some documentation from nsLookAndFeel.h
* Run `rg 'eColorID_' | cut -d : -f 1 | sort | uniq >files`
* Run the second script attached to the bug.
* Manually fix usage of `LAST_COLOR` (adding the `End` variant), and adding
casts to integer as needed.
* Add an static assert so that people remember to update the prefs, rather than
a comment on the definition :)

Include missing dependency requirements
Running `servo-tidy` in a virtualenv where all you've done is `pip install servo-tidy==0.3.0` doesn't actually work because of missing dependencies. PyYAML and voluptuous are required as well. I don't know anything about python package management but declaring these missing dependencies seems like an appropriate thing to do. Patch itself is untested because I don't know how, although with these dependencies installed in my virtualenv running `servo-tidy` works.
