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: Implement the <br> element for line breaking The <br> element will produce a special LayoutBreak node in the layout tree, which forces a break in the line layout whenever encountered. This patch also makes LayoutBlock use the current line-height as the minimum effective height for each line box. This ensures that having multiple <br> elements in a row doesn't create 0-height line boxes.

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

GC_DECLARE_ALLOCATOR(HTMLBRElement);
LibWeb: Add a whole bunch of HTML DOM bindings Note that these aren't full implementations of the bindings. This mostly implements the low hanging fruit (namely, basic reflections) There are some attributes that should be USVString instead of DOMString. However, USVString is a slightly different definition of DOMString, so it should suffice for now.
