[turbofan] Fix bailout for script context creation.

[turbofan] Fix bailout for script context creation.

This fixes the bailout point used by JSCreateScriptContext nodes for
top-level code. The bailout point differs from the Crankshaft one as
parameter slots have not been copied and the context chain was not
extended yet in TurboFan. Hence a new bailout id is required.
