[android] update AOT profile for .NET 9 Preview 7

[jonathanpeppers]

Context: https://github.com/jonathanpeppers/Mono.Profiler.Android/releases/tag/9.0.0-preview.1

I had to build dotnet/runtime from source and update the Mono.AotProfiler.Android NuGet package for this to work again.

Is it faster? do we want for the other preview7 pr to merge and run this again ?

I recorded this profile on a branch using net9.0 + this PR on top:

• [net9.0] Update preview7 packages #23809

So, it should be near the "final" Preview 7 build.

Is it faster?

I ran out of time yesterday, will check it today.

I think it is quite a bit better, dotnet new maui on a Pixel 7:

Before:
Average(ms): 471.1
Std Err(ms): 5.90188293870882
Std Dev(ms): 18.6633925700078
After:
Average(ms): 424
Std Err(ms): 4.40958551844098
Std Dev(ms): 13.9443337755679

I think the .NET 9 profile was last updated like Preview 4 or something.

@kg put in a lot of work to try to improve wasm startup it is possible some of the improvement is from that

@lewing it's on my list to compare .NET 8 vs .NET 9, so I don't know the results from that yet.
