LibWeb: Add the SubtleCrypto interface Just some boilerplate code to get started :^) This adds both the SubtleCrypto constructor to the window object, as well as the crypto.subtle instance attribute.

/*
LibWeb: Replace GlobalObject with Realm in wrapper functions Similar to create() in LibJS, wrap() et al. are on a low enough level to warrant passing a Realm directly instead of relying on the current realm from the VM, as a wrapper may need to be allocated while no JS is being executed.

LibWeb: Implement SubtleCrypto.digest() This is a simple implementation of SubtleCrypto.digest() using LibCrypto under the hood, so it supports all the required hash functions: SHA-1, SHA-256, SHA-384, SHA-512. Two FIXMEs remain: doing the hashing "in parallel", and supporting an object argument instead of a plain string.

LibWeb: Put most LibWeb GC objects in type-specific heap blocks With this change, we now have ~1200 CellAllocators across both LibJS and LibWeb in a normal WebContent instance. This gives us a minimum heap size of 4.7 MiB in the scenario where we only have one cell allocated per type. Of course, in practice there will be many more of each type, so the effective overhead is quite a bit smaller than that in practice. I left a few types unconverted to this mechanism because I got tired of doing this. :^)

LibJS: Make Heap::allocate<T>() infallible Stop worrying about tiny OOMs. Work towards #20449. While going through these, I also changed the function signature in many places where returning ThrowCompletionOr<T> is no longer necessary.

LibWeb+Meta: Add wrapper for the BufferSource/ArrayBufferView IDL types These wrappers will make it much easier to do various operations on the different ArrayBuffer-related classes in LibWeb compared to the current solution, which is to just accept a Handle<Object> everywhere (and use "any" in the *.idl files).
