  [iOS] Update SPI headers for iOS 17.4
https://bugs.webkit.org/show_bug.cgi?id=268210
rdar://problem/121706323

Reviewed by Jonathan Bedard and Alexey Proskuryakov.

Add platform flags for libxpc (which is API as of iOS 17.4+) and for
other SPI that were promoted to API as part of the BrowserEngineKit
introduction. Use them to avoid redeclaring things that are now
publicly available.

Additionally, write new BrowserEngineKit SPI declarations for symbols
that are used in testing and by SPI clients of WebKit.
