-----------
[GTK][WPE] Reduce use of WTF_ALLOW_UNSAFE_BUFFER_USAGE in PNGImageDecoder
https://bugs.webkit.org/show_bug.cgi?id=324990
Reviewed by Justin Michaud.
Narrow down the locations containing unsafe buffers usage in the PNG
image decoder, modernizing the code to use std::array and std::span more
extensively along with existing helper functions that operate on spans,
and a few helpers defined specifically for PNG chunk data.
No new tests needed, convered by existing tests.
