CI: Don't cancel the entire job matrix when one of them fails
By default, GitHub Actions [cancels][1] all in-progress jobs in a build matrix when one of them fails. This PR disables this behavior.

The "process the iframe attributes" steps shouldn't enqueue the iframe load event steps (anymore)
Fixes `HtmlIFrameElement::process_the_iframe_attributes` (which implements [the "process the `iframe` attributes" steps][1]) queueing an element task to execute [the iframe load event steps][2], which causes another `load` event to be fired on the iframe in addition to the one asynchronously generated by [the "create a new nested browsing context" steps][3].
The following timeline shows what happens when a `src`-less `iframe` element is parser-inserted and which step this PR intends to remove. (This does not necessarily match Servo's current behavior exactly - Most notably, `T2`'s steps might run late because the "create a nested browsing context" steps' implementation actually [parses][5] a blank HTML document.)
```diff
T0 (networking task source)
| Insert the `iframe` element, causing the following steps to be executed:
| | Create a new nested browsing context
| | | Create a new browsing context
| | | | Completely finish loading the `iframe` element's `Document`
| | | | | Queue element task T2.
| |
| | Process the `iframe` attributes
- | | | Queue element task T1
- T1 (DOM manipulation task source)
- | Execute the `iframe` load event steps
- | | Fire `load` for the `iframe` element
T2 (DOM manipulation task source)
| Execute the `iframe` load event steps
| | Fire `load` for the `iframe` element
```
This bug likely originates from [a bug][4] in the specification.

This likely originates from a bug that existed in the specification[1].
A `src`-less iframe would fire two `load` events when implemented
according to an affected version of the specification.

The initial document creation does not involve navigation, and it would
cause a confusion if this was done by a function which has `navigation`
in its name. This commit renames `navigate_or_reload_child_browsing_
context` to `start_new_pipeline`, and introduces a new function which
has the original name and is dedicated to handle navigation.
Implement `Location`'s custom internal methods
This PR partly resurrects #16501 and introduces the use of principals object to associate objects and Realms with origins. Using this infrastructure, this PR implements [the custom internal methods][1] of the `Location` interface, which is "maybe-cross-origin".
Unimplemented/incomplete things:
- Other maybe-cross-origin interfaces, namely `WindowProxy` and `DissimilarWindowLocation`, aren't implemented correctly yet (causing most test cases of `tests/wpt/web-platform-tests/html/browsers/origin/cross-origin-objects/cross-origin-objects.html` to fail).
- `WindowProxy`: #28556
- [The "perform a security check" operation][2] and `Location`'s non-cross-origin properties' relevant `Document` origin checks aren't implemented either (not sure if they are covered by the existing tests).
- There are a slight deviation from the standard and inefficiency in `CrossOriginGetOwnPropertyHelper`'s current implementation.
- #28557

There are code fragments in `(Method|Attr)Definer.generateArray` that
are much alike. This commit refactors them into a new method of
`PropertyDefiner` named `generateUnguardedArray` (in contrast to the
existing method `generateGuardedArray`).
It's technically safe to do because of `#[repr(transparent)]` and is a
prerequisite of having `ServoJSPrincipalsRef: Copy`, but I guess it's
not worth an `unsafe` block.
Shorten thread names to prevent information loss
The Linux kernel [imposes][1] a 15-byte limit on thread names. This means information that does not fit in this limit, e.g., the pipeline ID of layout and script threads, is lost in a debugger and profiler (see the first column of the table below).
This commit shortens the thread names used in Servo to maximize the amount of information conveyed. It also rectifies some inconsistencies in the names.

Fixes the following assertion from `tests/wpt/web-platform-tests/html/
browsers/origin/cross-origin-objects/cross-origin-objects.html`:
assert_equals(Object.keys(win.location).length, 0,
"Object.keys() gives the right answer for cross-origin Location");
No improvements are seen in `/html/browsers/origin/cross-origin-
objects/cross-origin-objects.html` because each included test case
tests both `Location` and `WindowProxy`, the latter of which isn't
implemented correctly yet. In fact, the first test case "Basic sanity-
checking" passes if it's reduced to only check `Location` as follows:
addTest(function(win) {
assert_equals(B.location.pathname, path, "location.href works same-origin");
assert_throws("SecurityError", function() { win.location.pathname; }, "location.pathname throws cross-origin");
}, "Basic sanity-checking");
Setting the lazy proto option allows proxy handlers to provide dynamic
prototype objects. This is necessary for the customization of
`ProxyTraps::{get,set}PrototypeOf` to actually take effect.
