This resolves an issue which can occur when using Xcode 26 Beta with the downloadable Metal toolchain installed, if a target imports Swift Testing. A toolchain override is specified in this scenario, and this causes the existing logic modified by this PR to incorrectly believe it's using a non-Xcode toolchain, which in turn causes the wrong Swift macro plugin flags to be passed, ultimately leading to a failure locating the
TestingMacrosplugin.The fix is to recognize all toolchains which have Xcode's prefix, and ensure the default toolchain prefix is used whenever any Xcode toolchain is in use.
