While system heap and system_cc_shared heap share a lot of code and hence the same source file, their users have different needs.
system heap users need it to be a loadable module, while system_cc_shared heap users don't.
Building as a loadable module breaks system_cc_shared heap on powerpc and s390 due to un-exported set_memory_encrypted / set_memory_decrypted functions.
Fix these by reorganising code to put the system_cc_shared heap under a new Kconfig symbol, which allows either building both into the kernel, or leave encryption up to the consumers of the system heap.
