[android] add AOT profile for dotnet new maui -sc

[jonathanpeppers]

There is a new "sample content" switch for the dotnet new maui template that brings in various NuGets and things automatically.

None of these things are in the built-in AOT profile, so let's record one specifically for this template. I also updated the other AOT profiles, as I can see some of the latest changes in dotnet/main/main calls different methods on startup.

Testing an average of 10 runs on a Pixel 7 Pro:

$ dotnet new maui
Before:
Average(ms): 446
Std Err(ms): 2.28035085019828
Std Dev(ms): 7.21110255092798
After:
Average(ms): 441
Std Err(ms): 5.09901951359278
Std Dev(ms): 16.1245154965971

$ dotnet new maui -sc
Before:
Average(ms): 1073.6
Std Err(ms): 8.35623519694525
Std Dev(ms): 26.4247358864127
After:
Average(ms): 832.1
Std Err(ms): 5.65773806392625
Std Dev(ms): 17.8913386866383

Since dotnet new maui -sc is still a bit slower, I will investigate how to improve this in other PRs.
