Frontend: re-serialise static library status

Browse Source 
When compiling the swiftmodule from the textual swift interface, ensure
that we re-serialise the static or dynamic nature of the module. This is
required for proper code generation where the static and dynamic linking
is material to symbolic references. This also opens the possibility of
optimizations on other platforms via internalisation of the symbols.

Fixes: #77756
