REGRESSION (300681@main): [visionOS] Web process crashes when editing any text
https://bugs.webkit.org/show_bug.cgi?id=300277
rdar://162071389
Reviewed by Abrar Rahman Protyasha and Aditya Keerthi.
Instead of `MESSAGE_CHECK`-ing as a result of failing to decode a custom web
font descriptor in
`FontWrapper::createFromIPCData`, fall back to the system font using
`CTFontCreateUIFontForLanguage`.
This primarily affects visionOS, which requests document editing context data
with attributed text
while the user types.
Test: Tools/TestWebKitAPI/Tests/WebKitCocoa/DocumentEditingContext.mm
* Source/WebCore/editing/cocoa/AttributedString.mm:
(WebCore::AttributedString::FontWrapper::createFromIPCData):
* Tools/TestWebKitAPI/Tests/WebKitCocoa/DocumentEditingContext.mm:
(TEST(DocumentEditingContext, RequestAttributedTextWithCustomFont)):
Add an API test that exercises this behavior by requesting
`UIWKDocumentRequestAttributed` in an
editable container with a custom font (Ahem).
