CreateInterpreterDataForDeserializedCode checks for bytecode, copies the
InterpreterEntryTrampoline, and installs that and the bytecode on
InterpreterData. However, the bytecode can be flushed when the IET is
copied, which results in a failure to read it afterward.

Add an IsCompiledScope to guard against this.

As a drive-by, guard against baseline code being installed on the
function. This shouldn't happen in normal execution, but could
theoretically happen with some extra support for --always-sparkplug.
