…mode This allows us to work around the following issue in CI: The self-hosted SwiftPM job has Xcode 15.3 (Swift 5.10) installed and builds a Swift 6 SwiftPM from source. It then tries to build itself as a fat binary using the just-built Swift 6 SwiftPM, which uses xcbuild from Xcode as the build system. But the xcbuild in the installed Xcode is too old and doesn't know about Swift 6 mode, so it fails with: SWIFT_VERSION '6' is unsupported, supported versions are: 4.0, 4.2, 5.0 (rdar://126952308). This is fixed by setting `SWIFTSYNTAX_DISABLE_SWIFT_6_MODE` in `build-using-self`. The source compat suite is seeing the same issue, just by using `bootstrap`, so set it there as well.

…ift 6 mode (#7500) Companion of swiftlang/swift-syntax#2627 - **Explanation**: This allows us to work around the following issue in CI: The self-hosted SwiftPM job has Xcode 15.3 (Swift 5.10) installed and builds a Swift 6 SwiftPM from source. It then tries to build itself as a fat binary using the just-built Swift 6 SwiftPM, which uses xcbuild from Xcode as the build system. But the xcbuild in the installed Xcode is too old and doesn't know about Swift 6 mode, so it fails with: SWIFT_VERSION '6' is unsupported, supported versions are: 4.0, 4.2, 5.0 (rdar://126952308). This is fixed by setting `SWIFTSYNTAX_DISABLE_SWIFT_6_MODE` in `build-using-self`. The source compat suite is seeing the same issue, just by using `bootstrap`, so set it there as well. - **Scope**: The build of SwiftPM using the `bootstrap` and `build-using-self` scripts - **Risk**: All issues that might have been caused by this will be found at build time - **Testing**: Verified that both the self hosted Swift CI job and the source compat suite build fine with #7495 - **Issue**: rdar://125579439 - **Reviewer**: @MaxDesiatov on #7495
