Part of #10799

Summary

Adds ACW (Android Callable Wrapper) support to TypeMap proxy types, building on the groundwork from PR #10808.

Changes

  • UcoMethodData/UcoConstructorData/NativeRegistrationData model types
  • ModelBuilder: generates UCO method wrappers, constructor wrappers, and native method registrations for ACW types
  • TypeMapAssemblyEmitter: emits [UnmanagedCallersOnly] UCO methods, UCO constructor wrappers, RegisterNatives, IAndroidCallableWrapper interface implementation
  • IsAcw detection for types that need JNI native method registration
  • Cross-assembly IgnoresAccessChecksTo for UCO callback types

Tests

  • Tests for all UCO/RegisterNatives generation scenarios (ACW detection, UCO methods, UCO constructors, native registrations)

- ModelBuilder: generates UCO method wrappers, constructor wrappers,
  and native method registrations for ACW types
- TypeMapAssemblyEmitter: emits [UnmanagedCallersOnly] UCO methods,
  UCO constructor wrappers, RegisterNatives, IAndroidCallableWrapper
- IsAcw detection for types that need JNI native method registration
- Cross-assembly IgnoresAccessChecksTo for UCO callback types
- Tests for all UCO/RegisterNatives generation scenarios

Address review findings: fix tests, deduplicate JNI parsing

- Fix UCO attribute test to verify actual UnmanagedCallersOnlyAttribute
  type name instead of just Assert.NotEmpty(attrs)
- Replace non-asserting NegativeEdgeCase Theory with three Facts that
  each assert a specific expected behavior
- Remove duplicate SkipSingleType method; ParseParameterTypeStrings
  now reuses ParseSingleType to advance the index
