Compress the unused pattern placeholder images more strongly (#69540)
* perf: Compress the unused pattern placeholder images more strongly
Seventeen placeholder images in plugins/woocommerce/assets/images/
pattern-placeholders are no longer loaded by any pattern. #68132 removed
the patterns but kept the files, because pages built from them still
link to the files.
Compress them harder, keeping names and formats so those links work.
The 15 JPEGs go through jpegoptim at maximum quality 50, and the
2.5k-px one is resized to 1920 px wide first. The 2 PNGs get a smaller
palette with pngquant.
The package shrinks by 1013 KB (62%). The checks are in the PR description.

* chore: Add changelog entry for compressing unused pattern placeholders
Adds the performance changelog entry required for the plugin package.

* chore: Make the placeholder optimization changelog entry comment-only
Nothing here changes what merchants see, so the entry carries a Comment
and no message, like the other changelog entries for asset cleanups.

* perf: Compress each unused placeholder as far as SSIM 0.96 allows
The first version used one setting for every file, which left some
files noticeably rougher than others (the lowest SSIM against trunk
was 0.925) and others with room to spare.
Pick the strongest setting per file that keeps the luma SSIM against
the trunk copy at 0.96 or better, and that also scores at least 60
on ssimulacra2 so a single metric cannot approve a bad image. Names,
formats and dimensions stay the same except for the one photo that
is resized to 1920 px.
The 17 files now total 602 KB instead of 1636 KB, down 63%.
