Remove usage of phf_macros.
It’s a compiler plugin that uses unstable compiler APIs that are not on a path to stabilization.
With this changes, there is one less thing that might break when we update the compiler. For example: https://github.com/sfackler/rust-phf/pull/101

Also remove the obsolete `--cpu` and `--gpu` renderer flags,
which also are no longer used.
Update tests and wptrunner to not pass these flags.
wptrunner changes have been upstreamed in:

Fix#14497: WeakMediaQueryListVec assumes its contents are still alive
<!-- Please describe your changes on the following line: -->
First time contributor here. Noticed this issue is easily solved, so I did it. I am very unsure about how things work here: Is a test needed? What should it look like? Should the "unwrap" be avoided (making bigger changes to the code)?

Implement downloadable fonts on Windows
This PR implements downloadable font support for Servo. It depends on new changes in webrender and dwrote, and adds a dependency on the `truetype` crate for pulling out basic font information. The original DirectWrite API does not provide an easy way to query font information direct from a `FontFace` (which is what you create from a `FontFile`). There are new DirectWrite APIs starting with Windows 10 that allow for this, but they are Win 10+ only, and `winapi-rs` does not yet have bindings for those versions of the interfaces (specificially, `IDirectWriteFontFace3`). The way to do this with DW is to go through a lot of pain in creating a custom collection and enumerator, add your font to your custom collection, then query the collection for its properties.
Instead, we just parse the truetype tables directly to pull out the few bits of information that we need. The `truetype` crate is ok, but I discovered some bugs (an update needs to get pushed to crates.io before this will build). It might be more worthwhile to just implement the tiny bit of truetype parsing that we need ourselves in Servo.
I'm guessing there are existing tests for downloadable fonts...

Make offset parent queries less buggy.
<!-- Please describe your changes on the following line: -->
Offset parent queries, which are used in the getters for HTMLElement's `offsetParent`, `offsetTop`, `offsetLeft`, `offsetWidth`, and `offsetHeight`, are pretty busted. The most egregious bug is that, as reported in #12939, inline elements are treated as if they're not present in the document. This PR fixes that and all of the other bugs I could trace directly to the offset parent query code, but `offsetTop` and `offsetLeft` are still unreliable in certain circumstances for reasons I haven't looked into (#13708). Inline elements with no content are still treated as not present due to #13982, so #13944 isn't fixed with this PR, either.

It’s a compiler plugin that uses unstable compiler APIs
that are not on a path to stabilization.
With this changes, there is one less thing that might break
when we update the compiler. For example:
https://github.com/sfackler/rust-phf/pull/101
Per https://html.spec.whatwg.org/multipage/embedded-content.html#dom-img-width:
The IDL attributes width and height must return the rendered width and
height of the image, in CSS pixels, if the image is being rendered, and is
being rendered to a visual medium; or else the density-corrected intrinsic
width and height of the image, in CSS pixels, if the image has intrinsic
dimensions and is available but not being rendered to a visual medium; or
else 0, if the image is not available or does not have intrinsic dimensions.
Ensure FrameState consistency
<!-- Please describe your changes on the following line: -->
As we begin to add more state to `FrameState`, we need to make sure that when we do replacements and when we finish traversals that the state is properly updated. This also fixes an issue where we were not updating the `url` of the `FrameState` when navigating with replacement enabled (I wonder if it would be possible to write a test to detect this. The url only matters when reloading a document after it was discarded by the max session history).

Use Box<CalcLengthOrPercentage> in specified values to avoid bloating inline sizes
For #15061
CalcLOP is a large struct, and gets used quite often. While #15063 reduces its size a bit,
it will still be much larger than any of the other variants in the `specified::Length*` types,
so it will still bloat sizes, especially for specified values that contain many lengths.
This change boxes it in the length types, so that it just takes one word.

Only create scrolling overflow regions when necessary
Only create scroll roots for overflow regions when the overflow region
is actually larger than the container size. This prevents creating
scrolling roots for elements that do not have overflow scroll as a
side-effect of the way their height and width is defined. For example,
tables should never respect overflow:scroll since their height and
width should always be large enough to prevent overflow. This also
decreases the size and complexity of the display list in many other
circumstances.
As part of this change, transformed overflow calculation is moved from
display list construction to layout. This should mean that overflow is
handled more accurately earlier.
Fixes#14574.
