fonts: Remove web fonts when their stylsheet is removed (#32346)

Browse source 
This is the first part of ensuring that unused fonts do not leak. This
change makes it so that when a stylesheet is removed, the corresponding
web fonts are removed from the `FontContext`.

Note: WebRender assets are still leaked, which was the situation before
for all fonts. A followup change will fix this issue.

Fixes #15139.
