The 'font: ...' shorthand is much more concise than setting each property separately: This replaces e.g. `"font-family:DejaVu Sans;font-size:12px;font-style:book;font-weight:book;"` by `"font: 400 12px 'DejaVu Sans'"`. Note that the previous font weight was plain wrong... Also this revealed a bug in generate_css (we shouldn't run it through escape_attrib, as quotes (e.g. around the font family name) get mangled); and we don't need to load the font at all (we should just report whatever font the user actually requested).

We currently special-case the SVG converter depending on if it used fonttype='none', and use one that has our base fonts available. However, this is not based on the rcParam setting (because we don't have that at conversion time), but on whether the SVG text contains the font styling [1]. This check for styling uses the _current_ version, which was changed way back in matplotlib#19253. These files were never re-generated though, and used the old version of the style, meaning the expected images never triggered the special converter. The result images are written with the current style, and _do_ trigger the special conveter. Evidentally, this never was a problem for most developers, because everyone had DejaVu Sans installed globally, so the expected images matched. However, on the clean macOS CI, it's not installed globally, so the expected images get converted with the wrong font, and the test fails.

The 'font: ...' shorthand is much more concise than setting each

"font-family:DejaVu Sans;font-size:12px;font-style:book;font-weight:book;"by
"font: 400 12px 'DejaVu Sans'".Note that the previous font weight was plain wrong...
Also this revealed a bug in generate_css (we shouldn't run it through
escape_attrib, as quotes (e.g. around the font family name) get
mangled); and we don't need to load the font at all (we should just
report whatever font the user actually requested).
Split out of #19201, but also including the non-mathtext case.
