Don't enable dl use in static builds for r0.25 (#3394)

* Don't enable dl use in static builds

remove dladdr in static

* Swap dlerror defs

* - add NGRAPH_INTERPRETER_STATIC_LIB_ENABLE && NGRAPH_CPU_STATIC_LIB_ENABLE as compiler definitions

* Don't look for backends if static

* - add dummy function to register quantized concat and max_pool for static build

* Fix ifdef
