  Fix the iOS TestWebKitAPI build when using recent versions of libTAPI

Reviewed by Tim Horton.

On some recent versions of libTAPI, the `.tbd` parser no longer recognizes multiple platforms that
are listed in v2 `.tbd` files; this causes missing symbols when attempting to weak link
`TestWTFAlwaysMissing*` from (intentionally missing) test dylibs, which only have corresponding
library .tbd stubs but no binary. To work around this (and modernize our TBDs while we're at it),
adopt the newer v4 TBD format (which is supported on all iOS 16-aligned SDKs).

Since we support this TBD format in all configurations that build against iOS, we no longer need
separate versions of the TBD either, so we also take the opportunity to consolidate it into a single
(v4) TBD file.
