f76c614a84 LibWeb: Generate PseudoClass metadata 
The usual to/from-string functions, and metadata about whether the
pseudo-class is a a function or not, and what type of parameter it
takes.

cce50b1841 LibWeb: Add MathML Namespace to IDL Generator 
This will make the codegen produce code for MathML IDL that doesn't
fail to compile in confusing ways.

3f35ffb648 Userland: Prefer _string over _short_string 
As `_string` can't fail anymore (since 3434412), there are no real
benefits to use the short variant in most cases.

ec24d7555a LibWeb: Add a simple internals objects only available during testing 
This object is available as `window.internals` (or just `internals`) and
is only accessible while running in "test mode".

This first version only has one API: gc(), which triggers a garbage
collection immediately.

In the future, we can add more APIs here to help us test parts of the
engine that are hard or impossible to reach via public web APIs.

de1726caee BindingsGenerator: Only truncate generated files if they have changed 
Rework the write_if_changed logic to properly truncate the output file.
The original logic would not truncate the file, leading to extra junk
at the end of files if the IDL files shrunk between builds.

d94a0623d0 Meta: Truncate generated IDL source files 
3dd3120a8a changed open mode from Write to
ReadWrite, which stopped truncating files.

This could be noticed by building a slightly older branch, as compiling
it gave compile errors.

ecef13338e Meta: Only write first output file to depfile 
There's no advantage to writing more than one file, and it lets the
depfile work with older versions of ninja.

cb8664e2e1 LibWeb/BindingsGenerator: Fix the build 
I'm not sure why this didn't break on CI, but none of my machines were
able to build without this change.

3dd3120a8a Meta+BindingsGenerator: Only invoke BindingsGenerator once per IDL file 
This reduces the number of tasks to schedule, and the complexity of the
build system integrations for the BindingsGenerator. As a bonus, we move
the "only write if changed" feature into the generator to reduce the
build system load on generated files for this generator.

13d5d47b56 LibWeb: Implement the CSS all property 
This sets all longhand values to one of initial, inherit, unset or
revert. Note that revert is not supported yet, but will be soon.

9d7215c636 LibJS+LibWeb: Move IteratorOperations.h AOs to Iterator.h 
Rather than splitting the Iterator type and its AOs into two files,
let's combine them into one file to match every other JS runtime object
that we have.

5703833116 LibJS+LibWeb: Refactor GetIterator to use GetIteratorFromMethod 
This is an editorial change in the ECMA-262 spec. See:
956e5af

This splits the GetIterator AO into two AOs, to remove some recursion
and to (soon) remove optional parameters.

efa55673cd Meta/CodeGenerators+LibWeb: Add support for 'easing-function' CSS values 
This commit makes it possible to let properties accept easing functions
as values, which will be used in a later commit to implement
animation-timing-function.

dd073b2711 Meta/CodeGenerators+LibWeb: Implement parsing CSS easing functions 
This only implements the parser bits, no functionality is implemented,
and no properties are parsed because of this.

165abafb80 LibWeb: Add initial implementation of IntersectionObserver 
The main missing features are rootMargin, proper nested browsing
context support and content clip/clip-path support.

This makes images appear on some sites, such as YouTube and
howstuffworks.com.

7f90b0cab7 LibWeb: Don't override prototype on generated iterator prototypes 
Generated iterator prototypes already have the IteratorPrototype as
their prototype, but we were incorrectly hijacking them and rerouting
to ObjectPrototype.

Regressed in cfe663435e.

0e3fb39a0a LibWeb: Make 'optional BufferSource' IDL arguments actually optional 
Previously this was compiled to require an object despite the IDL file
specifying 'optional'.
This commit makes IDLGenerator respect this modifier, and fixes the only
affected instance.

cfe663435e LibWeb+LibJS: Don't lazily construct web prototypes in cell constructors 
It's not safe to allocate from the GC heap while in the constructor of a
GC heap cell. (Because if this ends up triggering a collection, we may
end up trying to call through an uninitialized vtable).

This was already done safely in the initialize() virtual in much of
LibJS and LibWeb. This patch moves the logic for prototypes, mixins,
and CSSStyleDeclaration as well.

Fixes a long-standing GC crash that was pretty easy to reproduce by
refreshing https://vercel.com/
