[clang] Update ObjC and Itanium maintainership (PR #177950)

[Aaron Ballman via cfe-commits]

https://github.com/AaronBallman created https://github.com/llvm/llvm-project/pull/177950

John is stepping down from both of these roles as well. We do not have a replacement for Itanium ABI at this time, but this PR leaves the section in the maintainers file so it's clear we need to fill it.

Akira Hatanaka has graciously agreed to step up for Objective-C, thank you!
