C/C++ library: move free/delete-only definitions to library

tautschnig · tautschnig · commit cc701cc7a3e1 · 2022-01-21T10:46:29.000Z
With the support of building initialisers while adding the library we
can move library-only symbols to the library. This avoids polluting the
initialisation function for all cases that don't actually use
memory (de-)allocation library functions.
