vowpal-wabbit: 9.0.1 -> 9.6.0

- flatbuffers removed as a dep as the upstream doesn't support installing with flatbuffer support currently and this is an experimental feature
- BUILD_TESTS workaround removed as upstream now properly understands BUILD_TESTING
- `eigen` is a new dependency in this release
- Removed `USE_LATEST_STD` as it was causing an ICE in clang when building on an m1 macbook and it is not strictly necessary for the package
