`OnceCell` is now part of the standard library and we'll be able to use
it once we upgrade rust. For now we can use the version that's shipped
behind a feature flag in rust. This removes a dependency on one crate.

CSS viewport removal
It was removed from the spec and it's disabled everywhere.
This also removes the meta viewport support (which was implemented on top), but that also had a single test and is disabled everywhere, so I'm not too concerned, it can be implemented again if / when needed.
- [x] `./mach build -d` does not report any errors
- [x] `./mach test-tidy` does not report any errors
- [x] These changes fix#26349
- [x] There are tests for these changes

This directory now contains third_party software that is vendored into
the Servo source tree. The idea is that it would eventually hold
webrender and other crates from mozilla-central as well with a standard
patch management approach for each.
Replace use of the deprecated RUST_SYMBOL_TO_JSID by SymbolId
<!-- Please describe your changes on the following line: -->
A simple replacement of a deprecated function, according to changes in https://github.com/servo/mozjs/pull/315
That removes the only build warning I saw when doing a clobber.

When turning DOM exceptions into `ErrorInfo` always try to stringify
the JavaScript value, even if it's an object that isn't a `DOMException`
or native exception. This means that exceptions that extend the `Error`
prototype are now stringified. The result is that test output for WPT
global assertion failures is more useful. For instance for the test
include-frames-from-child-same-origin-grandchild.sub.html:
Before:
```
uncaught exception: unknown (can't convert to string)
```
After:
```
uncaught exception: Error: assert_equals: expected 4 but got 3
```
- Mark some instances of unused fields and variables as as allowed,
when they are used for memory management.
- Remove the use of some deprecated function.s

```
The expression `crossOriginIframe.contentWindow.location.href = "new
href"` takes the following steps: (1) Get the setter for `href` by
invoking `[[GetOwnProperty]]` on `crossOriginIframe.contentWindow.
location`. (2) Call the setter, passing `crossOriginIframe.
contentWindow` and `"new href"`. Since the target `Location` is cross
origin, getting the setter succeeds only if the `CrossOriginWritable`
extended attribute is present on the `href` attribute, and it's present.
However, instead of `CrossOriginWritable`, `CrossOriginReadable` was
checked mistakenly.
Since `Location#href` has `CrossOriginWritable` but not
`CrossOriginReadable`, this bug rendered `Location#href` inaccessible
from a cross-origin document.
