    tests/swscale: exclude init time from benchmark
This was originally intended to also include performance gains/losses
due to complicated setup logic, but in practice it just means that changing
the number of iterations dramatically affects the measured speedup; which
makes it harder to do quick bench runs during development.

    tests/swscale: unref buffers before each iteration
Otherwise, we always pass frames that already have buffers allocated, which
breaks the no-op refcopy optimizations.

Testing with -p 0.1 -threads 16 -bench 10, on an AMD Ryzen 9 9950X3D:

 Before:
  Overall speedup=2.776x faster, min=0.133x max=629.496x
  yuv444p 1920x1080 -> yuv444p 1920x1080, flags=0x100000 dither=1
     time=9 us, ref=9 us, speedup=1.043x faster

 After:
  Overall speedup=2.721x faster, min=0.140x max=574.034x
  yuv444p 1920x1080 -> yuv444p 1920x1080, flags=0x100000 dither=1
    time=0 us, ref=28 us, speedup=516.504x faster

(The slowdown in the legacy swscale case is from swscale's lack of a no-op
refcopy optimizaton, plus the fact that it's now actually doing memory
work instead of a no-op / redundant memset)

    swscale/tests/swscale: always allocate frame in scale_legacy()
Legacy swscale may overwrite the pixel formats in the context (see
handle_formats() in libswscale/utils.c). This may lead to an issue
where, when sws_frame_start() allocates a new frame, it uses the wrong
pixel format.

Instead of fixing the issue in swscale, just make sure dst is always
allocated prior to calling the legacy scaler.

    swscale/tests/swscale: remove hardcoded dimension checks
Remove dimension checks originally added to please static analysis
tools. There is little reason to have arbitrary limits in this
developer test tool. The reference files are under control by the user.

This reverts f70a651b3f7 and c0f0bec2f20.

    swscale/tests/swscale: make auxiliary conversions bitexact and accurate_rnd
This prevents the propagation of dither_error across frames, and should
also improve reproducibility across platforms.

Also remove setting of flags for sws_src_dst early on, since it will
inevitably be overwritten during the tests.
