Slow builds on Mac M1

Description

Here are build logs for iOS and Android on a newly installed M1 running Ventura, net7 and VS Mac public GA builds.

In general Android takes anywhere from 130s to 300+s to build cold. iOS is slightly better around 110s.

Verified that CLI is also long.

When I installed clean I noticed that installing MAUI uses Rosetta. Wonder how much this impacts build perf.

@jinxinjuan so you are able to repro the ProcessAssemblies MSBuild task taking 7 minutes?

This is an Android-only build step, but you mention iOS?
