Implements the time sync client, which allows devices to reach out to other matter nodes to query time.
Because this feature is challenging to test in the CI, this PR also includes a runtime options provider implementation that allows the time cluster to fake having no system time, forcing a read out over the network.
Tests: The added tests MUST be run using the provided script runner because they require a specific network and app setup to work correctly. The first two tests are used to prove the platform time bypass is functional (test_SimulateNoInternalTime and test_HaveInternalTime). The next "test" sets up a second node to act as the trusted time source. test_SetAndReadFromTrustedTimeSource tests that the node can read from the trusted time source immediately after setting it up. test_ReadFromTrustedTimeSource tests that the values persist correct and the node can read from the trusted time source after reboot.
This PR also includes an expansion of the delegate API, which will allow platforms to supply their own time. Currently, this is done using the platform time abstractions to match the current style of the time sync server impl.
Setting gn arg time_sync_enable_tsc_feature to 0 will turn this feature off. Note that this does NOT control the zap feature map.
Fixes: #28271
