* fix(video): defer refresh teardown until hw encoder warms up

On macOS, hevc_videotoolbox (the only encoder there reporting
!latency_free()) can return no packet for its first encode call. The
OPTION_REFRESH check in run() tore the encoder down with
bail!("SWITCH") inside that window, so each new encoder was destroyed
before producing a frame and rebuilt about once a second. With H265
selected on macOS 27 / Apple silicon, the picture froze or the session
dropped every 1-3 minutes.

On macOS, once the encoder has been fed a frame, defer the refresh
until it emits its first packet. Before that there is no warm-up to
lose, so a refresh can still restart a stalled capturer. Other
platforms and every latency-free encoder behave as before. An encoder
that never emits is still switched away from by the unchanged
max_fail_times path. The only new state is one flag.

Verified on macOS 27.0 / 27.0.1, M5 Pro, 2560x1440 H265. Soaked for two
weeks on a 1.4.9-based build carrying this deferral:
- before: ~40 "no valid frame" and ~27 refresh teardowns per 60s
- after:  37 sessions, every "no valid frame" at times:1, so
          max_fail_times was never approached; H265 never lost

Fixes #16457
