Improve performance of font fetching
https://bugs.webkit.org/show_bug.cgi?id=294405
rdar://153920635
Reviewed by Chris Dumez.
In <https://commits.webkit.org/296142@main>, we improved the performance of
font registration in the WebContent
process, by only registering fonts on demand. This patch is further improving
the performance, but this time in
the UI process. Instead of creating the mapping between font names and URLs
in-process, this patch instead gets
this information from a system service, where this data already is prepared and
stored in memory. Local
measurements show that this is approximately 10x faster than doing it
in-process.
This patch also fixes an issue where we would not register all font files for a
given font family. This is
addressed by creating a mapping between font family names and font names, which
is sent to the WebContent
process.
