Christopher Decker 94ff335d76 avformat/os_support: fix return value of win32_rename ...

The return value of MoveFileExW was not being correctly interpreted,
see https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-movefileexw.

On Windows a failed rename over the file: protocol now surfaces as failed to rename file %s to %s:
Operation not permitted (ff_rename, libavformat/avio.c:867) plus an AVERROR(EPERM) return, where previously the muxer
reported success and the user was left with a missing or stale output file and no diagnostic. This affects the
write-to-temp-then-rename paths in hlsenc, dashenc, hdsenc, smoothstreamingenc, segment, and img2enc (e.g. HLS/DASH
playlist updates, -write_temp_file, segment list finalization).

Also, added unit tests to exercise the rename function.
