Genode platform fixes (#17521)

Browse source 
* Genode: move dyncall failures to runtime

Do not use the "error" pragma to warn that dynamic library loading is
not implemented, print a message at runtime and exit.

* Genode: use stricter dataspace type in page allocator

* Genode: remove compiler configuration from nim.cfg

Self-hosting Nim is not supported on Genode and defining the
cross-compilation environment can be done externally.

* Genode: use new mutex API

* Genode: call nim_component_construct as a C procedure

* Genode: implement echo for NimStringV2
