We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
This patch adds support for script elements with the type attribute set
to "module". As a first cut the changes are mainly focused around inline
scripts.

Previously we would simply check the an input string against a list of
mime type essences, ignoring that the input might not be a valid mime
type or contain parameters.
This patch moves the helpers into the MimeSniff namespace and properly
parses an input string before comparing the essence.
This allows the garbage collector to keep HTML::Script objects alive and
fixes a bug where a HTMLScriptElement could get GC'd while its code was
executing.
Unlike ensure_web_prototype<T>(), the cached version doesn't require the
prototype type to be fully formed, so we can use it without including
the FooPrototype.h header. It's also a bit less verbose. :^)
This is a monster patch that turns all EventTargets into GC-allocated
PlatformObjects. Their C++ wrapper classes are removed, and the LibJS
garbage collector is now responsible for their lifetimes.
There's a fair amount of hacks and band-aids in this patch, and we'll
have a lot of cleanup to do after this.
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.
We shouldn't delay the load event for scripts that we're completely
refusing to run anyway. Also, for scripts that have inline text content,
we don't need to delay them either, as they will become ready before
returning from "prepare script".
This makes the "load" event finally fire on lots of websites, including
Wikipedia. :^)
We previously had a bug where markup with unclosed script tags caused
the document load event to be delayed indefinitely. Fix this by only
marking script elements as delaying the load event once we encounter
the script end tag.
The environment settings object is effectively the context a piece of
script is running under, for example, it contains the origin,
responsible document, realm, global object and event loop for the
current context. This effectively replaces ScriptExecutionContext, but
it cannot be removed in this commit as EventTarget still depends on it.

Step 1 of the spec is to capture the <script> element's node document
into a local variable.
When I originally implemented this, I thought this was not necessary.
However, I realised that the script that runs can adopt the current
script element into a different document, meaning step 5.4 and 6 then
operate on the incorrect document.

Instead of firing up a network request and synchronously blocking for it
to finish via a nested event loop, we now start an asynchronous request
when encountering <script src>.
Once the script load finishes (or fails), it gets executed at one of the
synchronization points in the HTML parser.
This solves some long-standing issues with random unexpected events
getting dispatched in the middle of parsing.
This namespace will be used for all interfaces defined in the URL
specification, like URL and URLSearchParams.
This has the unfortunate side-effect of requiring us to use the fully
qualified AK::URL name whenever we want to refer to the AK class, so
this commit also fixes all such references.
Before this patch, HTMLScriptElement would cache the full script source
text in a String member, and parse that just-in-time via Document's
run_javascript() helpers.
We now follow the spec more closely and turn the incoming source text
into a ClassicScript object ("the script's script" in the spec.)
No major engine allows whitespace in the type when checking for
"module".
This was also reflected in the relevant web platform test, but not in
the spec.
The spec has been changed to match this behaviour: 23c723e3e9
