Swift: Add abstraction for compilation mode
Add a `CMAKE_Swift_COMPILATION_MODE` variable and corresponding
`Swift_COMPILATION_MODE` target property to control the compilation
mode. Select among `wholemodule`, `singlefile`, and `incremental`.
Add policy CMP0157 to remove the default `-wmo` flags in favor of the
abstract setting.
Issue: #25366
