[Fiber] Instrument the lazy initializer thenable in all cases (facebook#35521)

When a lazy element or component is initialized a thenable is returned
which was only be conditionally instrumented in dev when asyncDebugInfo
was enabled. When instrumented these thenables can be used in
conjunction with the SuspendOnImmediate optimization where if a thenable
resolves before the stack unwinds we can continue rendering from the
last suspended fiber. Without this change a recent fix to the useId
implementation cannot be easily tested in production because this
optimization pathway isn't available to regular React.lazy thenables. To
land the prior PR I changed the thenables to a custom type so I could
instrument manually in the test. WIth this change we can just use a
regular Promise since ReactLazy will instrument in all
environments/flags now
