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.

Fixes: #44287

Sadly, this is not landing cleanly on the v16.x branch; it depends on #43531
