Mike Ash 6606850232 [Runtime] Add option to remove override point for retain/release. ...

Add a `SWIFT_STDLIB_OVERRIDABLE_RETAIN_RELEASE` CMake option. When set to true, swift_retain/release and the other functions in InstrumentsSupport.h can be overridden by setting the appropriate global function pointer, as is already the case. When set to false, those function pointers are removed and the functions always go into the default implementation.

Set `SWIFT_STDLIB_OVERRIDABLE_RETAIN_RELEASE` to false when building the minimal stdlib, and set it to true otherwise by default.
