Explanation: This enables the InoutLifetimeDependence flag when building a toolchain with the new build system. As a result the flag will be enabled in the swift core module's swiftinterface file. (It's already enabled when building with the older system, which generates the OSS toolchains.)
Scope: Binaries which use MutableSpan instances
Original PR: #81923
Risk: Very low; CI toolchains have this flag turned on.
Testing: CI
