  Changed paths:

    M Source/WebCore/page/UserContentProvider.cpp

  Log Message:
  -----------
  Lookalike character sanitization does not work if content blockers are 
disabled through SPI
https://bugs.webkit.org/show_bug.cgi?id=250608

Reviewed by Tim Horton.

Allow lookalike character sanitization to remain active even if content 
blockers are disabled via
`-[WKWebpagePreferences _setContentBlockersEnabled:NO]`, by hoisting the logic 
out of
`ContentExtensionsBackend::processContentRuleListsForLoad` and into the call 
site in
`UserContentProvider` instead. This allows us to apply these adjustments, even 
in the case where
`contentRuleListsEnabled(initiatingDocumentLoader)` return `false`.

Changes covered by a new API test.

* Source/WebCore/contentextensions/ContentExtensionsBackend.cpp:
(WebCore::ContentExtensions::ContentExtensionsBackend::processContentRuleListsForLoad):
(WebCore::ContentExtensions::sanitizeLookalikeCharactersIfNecessary): Deleted.
* Source/WebCore/page/UserContentProvider.cpp:
(WebCore::sanitizeLookalikeCharactersIfNeeded):

Move this from `ContentExtensionsBackend` to `UserContentProvider`. No other 
change in behavior.

(WebCore::UserContentProvider::processContentRuleListsForLoad):
