This reverts commit 041ae1f8.

Reason for revert: Causes jumbo builds to fail because of duplicate GenerateBytecodeHandler definitions.

Original change's description:
> [builtins] Start adding byte code handlers to builtins
> 
> Adds a new build flag, v8_enable_embedded_bytecode_handlers, that adds
> the bytecode handlers to the BUILTIN_LIST macros.
> 
> Currently it's not connected up to the code-generation so it actually
> does nothing except expand the builtins table.
> 
> Bug: v8:8068
