Apple platforms macOS, iOS, tvOS, and watchOS can all share the same compiler information. Rename `Darwin-*` modules to `Apple-*` and load them all through `CMAKE_EFFECTIVE_SYSTEM_NAME`. This saves duplication of 4 * 21 compiler information modules. Issue: #17870

# The CMAKE_EFFECTIVE_SYSTEM_NAME is used to load compiler and compiler

# It is useful to share the same aforementioned configuration files and

# An example are the platforms supported by Xcode (macOS, iOS, tvOS,
|

# and watchOS). For all of those the CMAKE_EFFECTIVE_SYSTEM_NAME is
