Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *

LibHTML: Add support for <font color> This was pleasantly trivial to implement with the new support for presentational hints. :^)

LibWeb: Move HTML object model stuff into LibWeb/HTML/ Take a hint from SVG and more all the HTML classes into HTML instead of mixing them with the DOM classes.

LibWeb+LibJS: Make the EventTarget hierarchy (incl. DOM) GC-allocated 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.

LibGC+Everywhere: Factor out a LibGC from LibJS Resulting in a massive rename across almost everywhere! Alongside the namespace change, we now have the following names: * JS::NonnullGCPtr -> GC::Ref * JS::GCPtr -> GC::Ptr * JS::HeapFunction -> GC::Function * JS::CellImpl -> GC::Cell * JS::Handle -> GC::Root

LibWeb: Avoid many style invalidations on DOM attribute mutation Many times, attribute mutation doesn't necessitate a full style invalidation on the element. However, the conditions are pretty elaborate, so this first version has a lot of false positives. We only need to invalidate style when any of these things apply: 1. The change may affect the match state of a selector somewhere. 2. The change may affect presentational hints applied to the element. For (1) in this first version, we have a fixed list of attribute names that may affect selectors. We also collect all names referenced by attribute selectors anywhere in the document. For (2), we add a new Element::is_presentational_hint() virtual that tells us whether a given attribute name is a presentational hint. This drastically reduces style work on many websites. As an example, https://cnn.com/ is once again browseable.

virtual bool is_presentational_hint(FlyString const&) const override;
LibWeb: Route presentational hints through the CSS cascade Previously, presentational hints bypassed the regular cascade pipeline and wrote directly into `CascadedProperties` under `CascadeOrigin::Author`. That meant `var()` substitution and the invalid-at-computed-value-time fallback had to be duplicated in a separate per-element pass, which in practice missed the IACVT step and could leave a `GuaranteedInvalidStyleValue` in the cascaded properties. This caused a crash in downstream code that assumed the value had been resolved. This introduces an `AuthorPresentationalHint` cascade origin and feeds them through the cascade as normal declarations. This means that `var()` resolution now happens in only one place.
