This CL fully implements the DataView getters for the Uint8, Int8, Uint16, Int16, Uint32 and Int32 types in Torque, and removes the runtime implementation that is not needed anymore. There should be a light but visible performance increase compared to the former runtime implementation.

`SetBuildEmbedderGraphCallback`, unlike `SetWrapperClassInfoProvider`, assumes a monolithic embedder that can provide all necessary information. That is not the case for e.g. Node.js, which can e.g. provide multiple Node.js instances per V8 Isolate, as well as native addons that may allocate resources on their own.

Port e3e3480b Original Commit Message: The builtins table is an array of pointers to builtin code objects. It used to be located within the Builtins class, which itself was part of the Isolate. To enable faster isolate-independent access to builtin code objects, this CL moves the builtins table into the heap, at a constant known offset from the roots table. With this change, builtins can be accessed through the root pointer with a single instruction: mov reg, [kRootPointer, <offset to builtin>] TurboAssembler::LookupConstant is also extended in this CL to potentially shortcut the slow-ish constants table lookup: root constants are loaded through the root list, and builtin constants through the builtins table.

SharedFunctionInfos store their original function literal's id. This is also their index in the Script's SFI list. Since the function literal id is only needed for lazy compilation and live edit, we can calculate it on-the-fly by linear search in the Script SFI list, and save a field on the SFI. If this regresses compile performance, we could alternatively store the function literal id on the preparsed scope data as future work.
