[Mbed] Unit tests improvements (project-chip#11589)

* Reduce unit test coverage for mbed - remove dnssd testing * Fix TestConfigurationMgr_GetPrimaryMACAddress for Mbed platform * Add TestKeyValueStoreMgr for Mbed platform Fix ReadConfigValueBin function for Mbed platform - check buffer size * Move CloseIOCTLSocket() function to the right place * Fix InetEndPoint test - skip InterfaceNameToId checking for Mbed * Fix condtion in TestKeyValueStoreMgr * Changes restyle * Add note to skip tests for Mbed platform
