test: use real Poiyomi shader in Poiyomi-related tests

Install com.poiyomi.toon 9.3.64 via vrc-get and rewrite Poiyomi tests to
use the actual '.poiyomi/Poiyomi Toon' shader instead of the internal proxy.

- Add AssetUtility.IsPoiyomiImported() (shader + Poi.Tools.PoiImportExportChecker)
- Rewrite PoiyomiMaterialTests to use real shader with IsPoiyomiImported() guard
- Rewrite PoiyomiToonLitGeneratorTests to use real shader with IsPoiyomiImported() guard
- Add com.poiyomi.toon 9.3.64 to vpm-manifest.json
