This is a rebase of #17325 with `[replace]` entries removed, a bunch more dependencies updated, and some more compile fixes. Original work by @Eijebong, thanks a lot!

hi there!
on windows, this change properly scales a font's line height by its size.
previously, line height was not scaled to the font's size at all, which meant line heights become worse and worse the further you scaled away from the font's design size (in either direction, larger or smaller).
this change makes the `line_gap` ratio and size scale with the font size. i've hand checked that the new computed `line_gap` matches the effective heights in chrome and firefox when `line-height = normal` for a bunch of system fonts. (servo's rendering quality on windows is a different story, though).
i believe this also solves #16476.

Libfontconfig dependency is causing huge startup times in Android (20 seconds on each page load!). On other platforms fontconfig caches are already available or can be prebuilt on installation scripts, but this can't be done on Android. Updating libfontconfig dependency doesn't fix the problem either.
This PR gets rid of libfontconfig in Android. It queries available fonts and variations from Android System font configuration files. Android doesn't provide an API to query system fonts until Android O (which is very far from the minimum API right now...)

Depends on https://github.com/servo/unicode-bidi/pull/27 , which
upgrades `unicode-bidi` crate to `0.3.0`.
Summary of changes:
* Use `unicode_bidi::Level` (instead of `u8`) in all relevant places and
replace magic computations with (inline) method calls to Level API.
* Doing so required adding `unicode-bidi` crate dependency to two more
components here: `style` and `gfx`. IMHO, totally makes sense, as
replaces local integer manipulations/checks with well-tested ones
already available in a common dependency.

Scroll roots are no longer nested containers holding items, so instead
we need to track the offsets of each, carefully handling fixed position
items and stacking contexts that create new reference frames.
Additionally, we remove the complexity of the pre-computed page scroll
offset, instead opting to send script scrolls to the layout task in
order to more quickly have a ScrollState there that matches the
script's idea of the scroll world.
Fixes#16405.

This is a collection of commits improving the rendering of linear and radial gradients by making them conform more closely to the spec.
All commits are are independent and should work without the others.
These commits address the following issues:
* a956e3fd529715cc0ac39b23910f19e092c7c5a9 resolves#3908 but contains also some other necessary changes to `convert_gradient_stops`. The updated function has a few more copys but should be more correct. Maybe @pcwalton wants to comment since he has originally written the code.
* b230be8aaf318fb754cf58e5cd243087df2f7e0f partially solves #16638. (Partially because `border-image-outset` is not implemented. This is an older issue for border gradients: #15894.
To quickly catch regressions and see changes to gradients I have created [a set of twelve manual testcases](https://pyfisch.org/stuff/testcases-gradients.html) and placed them in a single file. Attached are two files. One shows how the gradients were rendered before the PR the other one with the changes applied.

Just use WebRender's ClipId directly. This will allow us to create and
use ReferenceFrames in the future, if we need to do that. It will also
make it easier to have Servo responsible for creating the root
scrolling area, which will allow removing some old hacks in the future.

I got a panic in Servo when I ran it with `RUST_LOG=debug`, which was due to `FT_Get_Postscript_Name` returning a null pointer.
I'm not sure how to add a test for this, so there is none right now.

This is the first step toward removing inherited clips in favor of
scroll roots for handling overflow and CSS clipping. This will allow us
to more easily handle elements that should not be clipped. While we are
still using inherited clips here, we now properly clip some types of
content that wasn't clipped before.
