Fix AOT compatibility warnings in VectorStoreTextSearch

- Add UnconditionalSuppressMessage attributes for IL2075/IL2060 warnings during AOT analysis
- Expand DynamicallyAccessedMembers to include PublicMethods for GetMethod reflection calls
- Maintains RequiresDynamicCode attribute to properly indicate AOT incompatibility
- Addresses AOT test failures where --warnaserror treats warnings as compilation errors

The reflection-based LINQ expression building is inherently incompatible with AOT compilation,
but these attributes allow the build system to handle this known limitation gracefully instead
of failing with cryptic errors. Regular and AOT compilation phases require different suppression
mechanisms - pragma directives for regular builds, UnconditionalSuppressMessage for AOT analysis.
