Tim Hunt 4b03530ca8 MDL-68191 CSS minification: apply upstream performance/accuracy fix
There was a bug with the code to strip comments.
https://github.com/matthiasmullie/minify/issues/317

Applying the fix as a Moodle-specific change for now, because the
effect is significant.

MDL-67115: php 74 compliance - implode() params order. Note this has been fixed upstream
by https://github.com/matthiasmullie/minify/pull/300 so, whenever this library is updated
check if the fix is included and remove this note.
MDL-68191: https://github.com/matthiasmullie/minify/issues/317 is a bug that stops
large sections of the CSS from being minimised, and also is a huge performance drain.
We have applied the fix sent upstream because the performance win is so big.
(E.g. one case I measured, with the bug was 40 seconds to minify CSS, with the fix was
a few seconds. This is one of the reasons Behat runs in the browser are so slow.)
Whenever this library is updated check if the fix is included and remove this note.
