we don't need to tag the call/jump with relocation info, as the builtin

The only way to generate a builtin call at snapshot time is via

Replace all but one Handle<T*>(T*) calls with ones that explicitly pass
in an Isolate.

Requires plumbing Isolate* through several Parser functions which
previously avoided it because of worries about accessing the heap off
the main thread. In all off-main-thread cases, isolate will be nullptr
and every such function asserts with:
DCHECK_EQ(parsing_on_main_thread_, isolate != nullptr);

Also deletes unused function ParseInfo::ReopenHandlesInNewHandleScope.

Original change's description:
> [wasm] Introduce jump table
> 
> This introduces the concept of a jump table for WebAssembly, which is
> used for every direct and indirect call to any WebAssembly function.
> For lazy compilation, it will initially contain code to call the
> WasmCompileLazy builtin, where it passes the function index to be
> called.
> For non-lazy-compilation, it will contain a jump to the actual code.
> The jump table allows to easily redirect functions for lazy
> compilation, tier-up, debugging and (in the future) code aging. After
> this CL, we will not need to patch existing code any more for any of
> these operations.
