[tests] enable .NET 7 LLVM tests without Profiled AOT

Context: dotnet/runtime#68914

We found that the issue with LLVM only occurs when using Profiled AOT.

This is enabled by default for `Release` builds in .NET 6+, so let's
try using `-p:AndroidEnableProfiledAot=false`.

This at least gets some of our LLVM test coverage running again.
