avutil/frame: use the maximum compile time supported alignment for strides

Browse Source 
This puts lavu frame buffer allocator helpers in sync with lavc's decoder frame
buffer allocator's STRIDE_ALIGN define.

Remove the comment about av_cpu_max_align() while at it as using it is not
ideal when CPU flags can be changed mid process.

Should fix ticket #11116.
