ISerialization methods should take in const jsi::Value& (facebook#56410)

Summary:

Missed when we first added the `ISerialization` interface. In JSI APIs,
`Value` is generally passed in as a const reference. This makes it clear
that the actual reference, not the referent, is const.

Fixing the serialization methods to be consistent with the rest of JSI.
