This commit implements the otPlatAlarmMicro* platform APIs in the Nexus simulation environment. It also transitions the simulation's internal time base from millisecond to microsecond granularity to ensure that both millisecond and microsecond alarms operate on a consistent and shared time reference. Changes include: - Enabled OPENTHREAD_CONFIG_PLATFORM_USEC_TIMER_ENABLE in Nexus config. - Updated Nexus::Core to use a 64-bit microsecond time base (mNow). - Implemented otPlatAlarmMicroGetNow, otPlatAlarmMicroStartAt, and otPlatAlarmMicroStop. - Refactored Nexus::Node to support separate millisecond and microsecond alarm instances (mAlarmMilli and mAlarmMicro). - Updated radio timestamps and PCAP logging to use the new high- resolution microsecond time base. - Adjusted simulation time advancement and alarm triggering logic to handle both alarm types correctly.
