[ncp] implement ncp version of otPlatDnssd (#10882)

This commit implements NCP based version of `otPlatDnssdGetState`. A unit test is added to verify the implementation. This commit also adjusts the unit test workflow to put the ncp unit tests into a separate item. The direct reason for this commit is that `otPlatDnssd` APIs haven't been implemented in `FakePlatform` and when `OT_PLATFORM_DNSSD` is turned, the build failed. Let's first run NCP unit tests separately and later try to merge the test items.
