79caca8ca2 LibJS: Allow multiple labels on the same statement 
Since there are only a number of statements where labels can actually be
used we now also only store labels when necessary.
Also now tracks the first continue usage of a label since this might not
be valid but that can only be determined after we have parsed the
statement.
Also ensures the correct error does not get wiped by load_state.

7081fb4eb0 LibJS: Make the default constructed reference invalid 
Since we have the to_reference method on every expression class we must
somehow communicate it did not actually return a reference.
This (ab)uses the fact that property name is only invalid with the
default constructor and already has is_valid().

198bb322ef LibWeb: Fix null dereference when assigning an ImageStyleValue via JS 
When parsing a CSS value in the context of a CSSStyleDeclaration
camelCase property setter, we don't necessarily have a Document to
provide the CSS parser for context.

So the parser can't go assuming that there's always a Document in the
ParsingContext. And ImageStyleValue can't go assuming that there's
always a Document either. This will require some more work to get things
right, I'm just patching up the null dereference for now.

840822b8f1 LibSymbolication+SystemMonitor: Show ELF object in stack 
This small patch allows SystemMonitor's Stack tab to show the name of
the ELF object to which the displayed address refers to. This gives a
bit more of contextual information to the viewer.

A better to show this is probably a table, but I'm not that familiar yet
with the GUI framework in general, so I'm keeping things simple.

d462a6720a LibWeb: Reimplement the <style> element following the spec 
We now follow the "update a style block" algorithm from the HTML spec
instead of using the ad-hoc CSSLoader mechanism.

This necessitated improving our StyleSheet and CSSStyleSheet classes as
well, so that's baked into this commit.

This adds automatic scrolling when dragging items in TreeViews and other
widgets that inherit from AbstractView when the overloaded
accepts_drag() returns true. This is implemented in FileSystemModel to
allow directories and files to be dragged.

3a4565beec LibWeb: Make CSSRule and CSSRuleList available to JavaScript :^) 
This patch makes both of these classes inherit from RefCounted and
Bindings::Wrappable, plus some minimal rejigging to allow us to keep
using them internally while also exposing them to web content.
