[Android] .NET 6 build/deploy performance should match Xamarin

[jonathanpeppers]

.NET 6 build/deploy performance is already pretty close to existing Xamarin.Android.

Example of a "hello world" app:

More commentary in Teams here.

We have Github issues tracking the current gaps we have:

• FastDev should alter $(RuntimeIdentifiers) for connected device android#5374
• [One .NET] improve Install target performance in IDEs android#5436

I have seen slightly faster build/deploy times with .NET 6 if I use --no-restore and a single $(RuntimeIdentifier). Completing the above work items would get the performance we want for default scenarios in IDEs.

I think the referenced issues are completed in .NET 6 Preview 3, going to close.
