[clang-tidy] introduce legacy resource functions to 'cppcoreguidelines-owning-memory'

Summary:
This patch introduces support for legacy C-style resource functions that must obey
the 'owner<>' semantics.

- added legacy creators like malloc,fopen,...
- added legacy consumers like free,fclose,...

This helps codes that mostly benefit from owner:
Legacy, C-Style code that isn't feasable to port directly to RAII but needs a step in between
to identify actual resource management and just using the resources.
