Erik Eckstein ef302ce4ac SILOptimizer: enable stack protection by default ...

The pass to decide which functions should get stack protection was added in https://github.com/apple/swift/pull/60933, but was disabled by default.

This PR enables stack protection by default, but not the possibility to move arguments into temporaries - to keep the risk low.
Moving to temporaries can be enabled with the new frontend option `-enable-move-inout-stack-protector`.
