Fix font-size-adjust toggling font sizes for 'system-ui' font.
https://bugs.webkit.org/show_bug.cgi?id=259895
rdar://111709567
Reviewed by Tim Nguyen.
When using 'system-ui' font, we will end up calling
FontFamilySpecificationCoreText::fontRanges for obtaining FontRanges
with an appended font.
Before this patch, ::fontRanges() was updating the font's size for the
font-size-adjust everytime fontRange was called. The update would mutate
the font that is cached. After the page is refreshed and this function
was called again, we would retrieve the cached font, and execute the
size adjustment again, what would cause the bug.
This patch moves the call to updateSizeWithFontSizeAdjust to the lambda
function invoked when the Font is being cached, guaranteeing it will be
called just once.
