lavc/vaapi_decode: Use dynamic frame pool if possible 

libva2 doesn't require a fixed surface-array any more, so we may use
dynamic frame pool for decoding when libva2 is available, which allows a
downstream element stores more frames from VAAPI decoders and fixes the
error below:

$ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi \
-i input.mp4 -c:v hevc_vaapi -f null -
...
[h264 @ 0x557a075a1400] get_buffer() failed
[h264 @ 0x557a075a1400] thread_get_buffer() failed
[h264 @ 0x557a075a1400] decode_slice_header error
[h264 @ 0x557a075a1400] no frame!
