Turn on the BUILD_LIBRARY_FOR_DISTRIBUTION flag

[matopeto]

Issue Link :link:

#4871

Goals :soccer:

Make the library "module stable" so compiled xcframework can be used in newer version of Xcode/swift without recompile

Implementation Details :construction:

Turned on the build setting BUILD_LIBRARY_FOR_DISTRIBUTION Also added @_implementationOnly to silence the warning described in #4871

Testing Details :mag:

I tested compiled xcframework with Xcode 13.4 and worked in Xcode 14
