libmaxminddb: update to 1.8.0.

## 1.8.0 - 2023-11-07

* `PACKAGE_VERSION` is now a private compile definition when building
  with CMake. Pull request by bsergean. GitHub #308.
* `PACKAGE_VERSION` is no longer defined in `maxminddb.h` on
  Windows.
* The feature test macro `_POSIX_C_SOURCE` is no longer set by
  `maxminddb.h`. As discussed in GitHub #318, this should be set by
  applications rather than by libraries.
* `assert()` is no longer used outside test code.
* The deprecated Visual Studio 12 project files in the `projects/`
  directory have been removed. CMake should be used when building on
  Windows.
