vout: don't reset displayed.timestamp on flush

This variable is not used anymore but will be used by next commits.
This timestamp is the original one coming from the decoder.

context

es_out: use vlc_input_decoder_StopFrameNext()

Call vlc_input_decoder_StopFrameNext() when resuming from next-frame, or
when flushing.
Rework EsOutStopNextFrame() to return the next frame es, to prevent it
for being flushed.

Not functional changes, as vlc_input_decoder_StopFrameNext() does
nothing.

es_out: add private ES_OUT_PRIV_RESET_PCR_FRAME_PREV

Will be triggered from decoders, when seeking to search for a previous
frame. The only difference with ES_OUT_RESET_PCR is that the frame
next/previous context is not stopped and we ensure we have enough
buffering to reach the previous frame.

input: add previous-frame support

Add `decoder_prevframe.c` that handle most of the previous-frame logic:
trigger a seek to `current_frame - n` (n is 1 at the start).

Store 1 decoded frame until we reach the current frame. When the
previous frame is found, return it and trigger another seek when needed.
In case the seek missed the current frame, increase n and trigger
another seek.

This solution doesn't require more memory, it is able to play backward
"in real-time" (when pressing the previous-frame key) most of 1080p
videos.

It is also able to play 4K 60FPS videos with few slow-downs (when seeking).

Fixes #10252

preparser: don't seek to invalid time/pos

Like it's done by vlc_player_t when using input_thread_t API.

Needed because the parser test seek to invalid position, and the next
commit will assert the seek time are valid.

mock: seek to deterministic audio/video pts

Respect video FPS and audio frame length when seeking.

Video PTS are now x(1/fps), even after a seek.
Audio PTS are now x(audio_sample_length), even after a seek.
