…e name collision

- Replace [DynamicDependency] attributes on FindX509TrustManager with a
  HackToPreserveInvokers method using [MethodImpl(NoInlining)] to prevent
  the linker from trimming IX509TrustManagerInvoker and
  X509ExtendedTrustManagerInvoker.
- Remove obsolete API 21-23 Conscrypt TrustManagerImpl workaround.
- Rename generated enum from AppFunctionState to AppFunctionEnabledState
  to avoid name collision with the new Android API 37
  android.app.appfunctions.AppFunctionState class.

When the getSuperclass() class hierarchy walk fails to find a
targetType-compatible TypeMap proxy (e.g., because an intermediate
class entry like X509ExtendedTrustManager was trimmed), fall back
to walking Java interfaces via getInterfaces() at each level of
the class hierarchy. This allows the runtime to find TypeMap entries
for Java interfaces (e.g., javax/net/ssl/X509TrustManager) that are
preserved by the trimmer but unreachable via getSuperclass() alone.

The interface walk only runs when targetType is an interface, keeping
the common path (class-based resolution) unchanged.

Also adds a device test TrustManagerFactory_GetTrustManagers_ReturnsIX509TrustManager
that verifies TrustManagerFactory.GetTrustManagers() returns elements
that can be cast to IX509TrustManager. This test runs on both
llvm-ir and trimmable typemap paths.

…es method ID

- Check interfaces inline during the getSuperclass() walk instead of
  a separate second pass, avoiding redundant GetObjectClass/getSuperclass calls
- Cache the JNI method ID for getInterfaces() in a static field
- Rename TryGetProxyFromInterfacesOfClass to TryMatchInterfaces

…ound

The [DynamicDependency] attributes on FindX509TrustManager are needed
by both llvm-ir and trimmable typemap paths to preserve invoker types.
Without them, the llvm-ir linker also trims X509ExtendedTrustManager
entries, causing the same IX509TrustManager resolution failure.

Removed the API 21-23 Conscrypt TrustManagerImpl workaround since
minimum supported API level is now higher.

Address review feedback: add coverage that all-MCW alias groups emit
a conditional (3-arg) base alias-holder entry, mixed ACW/MCW alias
groups stay unconditional (2-arg), and essential runtime types remain
unconditional regardless of peer types.

Replace raw JNIEnv.GetMethodID/CallObjectMethod/GetArrayLength/
GetObjectArrayElement/DeleteLocalRef with their JniEnvironment
equivalents (JniMethodInfo, JniObjectReference, JniEnvironment.Arrays,
JniEnvironment.InstanceMethods). This matches the style of the
surrounding hierarchy walk code and uses proper ref disposal via
JniObjectReference.Dispose.

Wrap the JNI class handle in Java.Lang.Class with DoNotTransfer
ownership and call the existing GetInterfaces() binding. This
reuses the JniPeerMembers method ID caching, thread-safe lookup,
and JNI remapping that the generated binding already handles.

… test

- Use DoNotTransfer | DoNotRegister when wrapping JNI class handles in
  Java.Lang.Class to avoid peer table registration overhead
- Remove extra blank line before GetProxyForJavaObject
- Remove verbose diagnostic logging from device test, keep only the
  assertion with descriptive failure message
- Remove unused Log import from test
- Keep hierarchy walk using JniObjectReference (not Java.Lang.Class) to
  avoid potential recursion into TypeMap during class resolution

Java.Lang.Class.GetInterfaces() returns Java.Lang.Class[] where each
element holds a global ref. Dispose them in a finally block to avoid
leaking grefs until GC collection.

Use JniEnvironment APIs consistently while walking Java interfaces and cache interface lookup results by Java class and target interface. This avoids repeated JNI reference churn in hot interface marshalling paths.

Include the trust-manager marshalling test in Mono.Android.NET-Tests and add an API-independent Java fixture that exercises base-interface return values whose concrete implementation advertises a derived interface.
