Create only one compartment for each script thread (agent)
Documents in the same [agent][1] can share and exchange JS and DOM objects freely, so putting them in separate compartments would require almost every instance of `Dom` to be capable of handling cross-compartment references.

This should (hopefully) eliminate the intermittent hang-ups in the test

Update toolchain to nightly-2021-05-18
The nightly-2021-03-12 toolchain doesn't have RLS on Windows. This
breaks code completion in Visual Studio Code because the rust plugin
picks up the project toolchain.
RLS is available in all tier one platforms in nightly-2021-05-18 per:

Bump rayon-core from 1.9.0 to 1.9.1
Bumps [rayon-core](https://github.com/rayon-rs/rayon) from 1.9.0 to 1.9.1.
<details>
<summary>Changelog</summary>
<p><em>Sourced from <a href="https://github.com/rayon-rs/rayon/blob/master/RELEASES.md">rayon-core's changelog</a>.</em></p>
<blockquote>
<h1>Release rayon 1.5.1 / rayon-core 1.9.1 (2021-05-18)</h1>
<ul>
<li>The new <code>in_place_scope</code> and <code>in_place_scope_fifo</code> are variations of <code>scope</code>
and <code>scope_fifo</code>, running the initial non-<code>Send</code> callback directly on the
current thread, rather than moving execution to the thread pool.</li>
<li>With Rust 1.51 or later, arrays now implement <code>IntoParallelIterator</code>.</li>
<li>New implementations of <code>FromParallelIterator</code> make it possible to <code>collect</code>
complicated nestings of items.
<ul>
<li><code>FromParallelIterator<(A, B)> for (FromA, FromB)</code> works like <code>unzip</code>.</li>
<li><code>FromParallelIterator<Either<L, R>> for (A, B)</code> works like <code>partition_map</code>.</li>
</ul>
</li>
<li>Type inference now works better with parallel <code>Range</code> and <code>RangeInclusive</code>.</li>
<li>The implementation of <code>FromParallelIterator</code> and <code>ParallelExtend</code> for
<code>Vec<T></code> now uses <code>MaybeUninit<T></code> internally to avoid creating any
references to uninitialized data.</li>
<li><code>ParallelBridge</code> fixed a bug with threads missing available work.</li>
</ul>

<!-- Please describe your changes on the following line: -->
This adds instructions for building servo on nixOS and the required shell.nix to prepare the environment
---
<!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `___` with appropriate data: -->
- [ ] `./mach build -d` does not report any errors
- [ ] `./mach test-tidy` does not report any errors
- [x] These changes fix#10468 (GitHub issue number if applicable)
<!-- Either: -->
- [ ] There are tests for these changes OR
- [x] These changes do not require tests because they relate to adding a new build environment, not any servo code
<!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.-->
<!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. -->
