cam: options: Avoid copies of OptionvValue and KeyValueParser::Options

The OptionValue toKeyValues() and toArray() functions return a copy of
the values. This is unnecessary, and can cause use-after-free issues
when taking references to the return values. Return references instead
to optimize the implementation and avoid issues.

The behaviour of the two functions is now undefined in case of an option
type mismatch. The current implementation catches this with an
assertion.
