SDK users who do not enable debug logging see no output when the
status waiter is running, even though the legacy waiter printed
resource-readiness progress to stdout. The statusWaiter's "waiting for
resources" and "all resources achieved desired status" messages were
both at slog.Debug level, invisible unless --debug is passed.
Promote these five calls to slog.Info so that SDK callers that set up
a logger at Info level (the default) see meaningful wait progress
without needing to enable debug.
The per-resource "waiting for resource" poll callback remains at Debug
since it fires on every poll cycle and would be too noisy at Info.
Fixes#31585
