Reland of [builtins] Introduce a builtin for Abort().

Original message:

Calling Runtime::kAbort through a builtin instead of the c-entry stub
will allow to generate the call in a background thread, because a
builtin provides its own handle, whereas a code stub does not.

@v8-mips-ports: Could you take a special look at the padding that is
done in MacroAssembler::Abort()?

Reason for revert:
The reason for reverting is: Blocks roll:
https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20arm64%20-%20sim%20-%20debug/builds/1622

The problem was that on arm64 the builtin for Abort() contained a call to
Abort(). The problem is fixed by using a NoUseRealAbortsScope in the
code generation of Abort().
