Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might change in the future. Shared arrays can be shared across Isolates, have a fixed size, have no prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays. The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

This merges the separate opcode name definitions from wasm-opcodes-inl.h into the main opcode-defining macros in wasm-opcodes.h. This is simpler (avoids a bunch of fairly complex macros) and easier to update when we add new opcodes in the future. The tests become obsolete because they would simply repeat the implementation.

Before we assumed that no exception can be thrown when specifying a function to be used as an async hook, but that's not the case when e.g. the object passed to createHook is a proxy trapping on property access and the trap throws an exception.

PopToModifiableRegister did not check the {pinned} list, so it could return a register which was already used for another (temporary) value. This CL fixes that, and adds a little optimization which gives more freedom to the choice of spilling and has a chance to avoid a register mode.

Previously, when embedders attempted to create ArrayBuffers backed by memory outside the sandbox, V8 would simply crash with a failed CHECK when converting the raw backing store pointer into a SandboxedPointer. The new ApiCheck now provides a better error message in that case.
