Context's default IsCodeGenerationFromStringsAllowed value can be
changed by v8 flag `--disallow-code-generation-from-strings`. Restore
the value at runtime when delegating the code generation validation to
`node::ModifyCodeGenerationFromStrings`.
The context's settings are serialized in the snapshot. Reset the setting
values to its default values before the serialization so that it can be
correctly re-initialized after deserialization at runtime.
