Rollout useRawPropsJsiValue (#53426)

Summary:
Pull Request resolved: #53426

Experiment review for this was completed internally, and we can now change the default behaviour to no longer allocate an intermediate folly::dynamic when parsing props.

RawValue will continue supporting a folly::dynamic constructor as some paths go through code path (eg animations)

There should be no user-visible difference in parsing behaviour.

Changelog: [Internal]
