avcodec/nvenc: change default H.264 profile from main to high
The NVENC H.264 high profile provides up to 16% bitrate savings
(BD-Rate measured with VMAF) compared to the main profile.
Since most users do not explicitly set a profile, changing the
default benefits the common case. Users requiring the main profile
for legacy decoder compatibility can still set it explicitly.
The change is gated behind a versioned define so it only takes
effect on the next major version bump (libavcodec 63).
