Optimize the placeholder images that Coming Soon patterns use (#69539)
* perf: Optimize the placeholder images that Coming Soon patterns use
Sixteen placeholder images in plugins/woocommerce/assets/images/
pattern-placeholders are still loaded by the four Coming Soon patterns.
Optimize them without changing names, formats or dimensions. 9
thumbnails go through jpegoptim and jpegtran and keep every pixel. The
three larger photos are re-encoded with Guetzli at its minimum quality,
84. The other 4 files are already as small as lossless optimization
can make them, so they are untouched.
The package shrinks by 44 KB (21%). The history of the files and the checks are
in the PR description.

* chore: Add changelog entry for optimizing in-use pattern placeholders
Adds the performance changelog entry required for the plugin package.

* perf: Keep every optimized placeholder at SSIM 0.98 or better
The first version of this change re-encoded three larger photos with
Guetzli at its minimum quality, and one of them scored an SSIM of
0.921 against its trunk version. That is lower than intended.
Pick the strongest setting per file that keeps the SSIM against the
trunk copy at 0.98 or better (ffmpeg luma SSIM): jpegoptim at a
per-file maximum quality, Guetzli where it wins, and lossless where
nothing smaller qualifies. Files that would only shrink by a few
bytes stay untouched.
The 16 changed files now total 165 KB instead of 236 KB, down 30%.
Names, formats and dimensions are unchanged.

* chore: Update changelog entry for the optimized in-use placeholders
Match the entry to the new total saving.

* 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.
