Removing NL Unit Infrastructure (project-chip#33943)

* removing nl_unit infra from ESP32

* removing nl_unit infra from Nordic

* removing nl_unit infra from OpenIoTSDK

* removing nl_unit infra from mbed

* removing nl_unit infra from EFR32

* removing include dependencies of nl_unit_test

* making Mbed Unit Tests return an Error to clarify that they are disabled

* adding issue number to code comment
