[mbed-os-5.15] Add system time read/write callbacks to mbed-mesh-api

14818

Summary of changes

connectivity tests: Early test skip

14771

Summary of changes

Adding mbed-os subdirectories that are not required for a specific project to .mbedignore is a good way to reduce compilation time. Sometimes it happens that tests depend on ignored files, which causes the test-build to fail even though the corresponding feature/component is not configured. The reason is that the conditional that skips the test is placed after the includes.
