librocdxg: Remove static DXCore library dependency

Remove static linking to libdxcore library from CMakeLists.txt.
This prepares for dynamic loading implementation and eliminates
hard dependency on DXCore being present at build time.

The DXCore functionality will be loaded dynamically at runtime
in subsequent patches, making the library more flexible for
different deployment scenarios.
