Propagate deferred registerNatives to base classes and fix test plumbing
- Propagate CannotRegisterInStaticConstructor through the base class chain so that base types like TestInstrumentation_1 also use the deferred __md_registerNatives() pattern instead of static { registerNatives(...); } which crashes before the managed runtime registers the JNI native. - Revert C++ host-jni.cc/hh registerNatives bridge — the managed [UnmanagedCallersOnly] registration in TrimmableTypeMap.RegisterNatives() handles this without needing a C++ bridge. - Add targetPackage default for instrumentation in ComponentElementBuilder. - Switch proxy base type to generic JavaPeerProxy<T> in TypeMapAssemblyEmitter. - Add CannotRegisterInStaticConstructor to JavaPeerProxyData model. - Normalize manifest android:name to actual JNI names. - Add test exclusions for TrimmableIgnore and SSL categories. - Add TRIMMABLE_TYPEMAP define constant for conditional compilation. - Add unit tests for base class propagation and manifest normalization.
