payload_count is used to track the number of SEI payloads. It is also
used to free the SEIs in cbs_h264_free_sei()/cbs_h265_free_sei().

Currently, payload_count is set after for loop is completed. Hence if
there is an error and the function exits, the payload remains zero
causing a memleak.

This commit keeps track of payload_count inside the for loop to fix the
issue. Note that that the contents of current are initialized with
av_mallocz() so there is no need to zero initialize payload_count.

There can be at most 31 SPS and 255 PPS in the mp4/Matroska extradata.
Given that each has a size of at most 2^16-1, the length of the output
derived from these parameter sets can never overflow an ordinary 32 bit
integer. So use a simple uint32_t instead of uint64_t and replace the
unnecessary check with an av_assert1.

These functions aren't available when building for the restricted
UWP/WinRT/WinStore API subsets.

Normally when building in this mode, one is probably only building
the libraries, but being able to build ffmpeg.exe still is useful
(and a ffmpeg.exe targeting these API subsets still can be run
e.g. in wine, for testing).

As the values generated by av_bmg_get can be arbitrarily large
(only the stddev is specified), we can't use a fixed tolerance.
Calculate a dynamic tolerance (like in float_dsp from 38f966b2),
based on the individual steps of the calculation.

This fixes running this test with certain seeds, when built with
clang for mingw/x86_32.
