Update Boost iOSX dep and make it work for arm and i386 for sims (#2341)

Summary:
This diff updates and adds the boost ios podspec in flipper repo. This new boost dep works for Arm and i386 archs for simulator too.

This diff also updates our GH Action to remove i386 from excluded archs. Still arm64 is kept as non M1 mac machines do not have arm swift symbols for arm simulator. And since all our CI is on non M1, it is required.

It also takes care of https://github.com/facebook/flipper/issues/2268
