      MSVC: Add abstraction for runtime library selection · fb3370b6
      Brad King authored
      Replace our hard-coded defaults for `/MD` and `/MDd` with a first-class
      abstraction to select the runtime library from an enumeration of logical
      names.  We've long hesitated to do this because the idea of "runtime
      library selection" touches on related concepts on several platforms.
      Avoid that scope creep by simply defining an abstraction that applies
      only when targeting the MSVC ABI on Windows.
      
      Removing the old default flags requires a policy because existing
      projects may rely on string processing to edit them and choose a runtime
      library under the old behavior.  Add policy CMP0091 to provide
      compatibility.
      
      Fixes: #19108
