I noticed there might be a performance regression in .NET 7 when
building a .NET MAUI project, in the `<GenerateJavaStubs/>` MSBuild
task:
.NET 6: GenerateJavaStubs = 799 ms
xa main: GenerateJavaStubs = 912 ms
When reviewing what PerfView shows, I saw:
54.31ms (5.7%) module java.interop.tools.javacallablewrappers <<java.interop.tools.javacallablewrappers!Java.Interop.Tools.TypeNameMappings.JavaNativeTypeManager.ToJniName(class Mono.Cecil.TypeDefinition)>>
This was the overload that did not take in a `TypeDefinitionCache`. I
found one instance of this in `<GenerateJavaStubs/>`.
This doesn't seem like the .NET 7 regression, because it has always
been this way.
However, it seems to help quite a bit:
GenerateJavaStubs = 825 ms
GenerateJavaStubs = 867 ms
This probably saves around ~50ms in this task.
