[Mono] Skip satellite assemblies during Java type generation

[Copilot]

Mono publishing passed packaged *.resources.dll assemblies to JLO and type-map readers despite satellite assemblies having no types or scanner sidecars. This caused sidecar lookup inside the originating NuGet package.

• Generation pipeline

  • Exclude satellite assemblies from Java callable wrapper, ACW map, and LLVM-IR type-map generation.
  • Preserve the original assembly set for packaging and other build stages.

• Regression coverage

  • Add a Mono package test that exposes a NuGet satellite without sidecar metadata to Java stub generation.
  • Verify the satellite remains packaged.
