Port update and consumers bump

Hello all,

I'm working on x11-toolkits/wxgtk32 update.

What's the correct method to do this wotk since it involves bumping
consumers?
Can't find it in Porter's handbook.

For now I did:

1. Update x11-toolkits/wxgtk32 and test build
2. Build consumers `portgrep -o USE_WX 3.2`
3. Run test some of consumers

I've noticed that Tools/scripts/bump-revision.sh exists but I've never used
it.

Any hints is welcome.

Thanks,
