Switch to new CodeCov uploader

The currently used bash uploader is deprecated and will be removed in
the future[1]. This commit replaces the existing setup with the new
uploader for all currently supported platforms as proposed in [2].

Additional notes:
- FreeBSD support isn't supported yet and keeps using the old uploader
- Moved the new implementation into a dedicated file `source`d by
  all coverage CI's (instead of changing each individual configuration)
