/// @brief Appends a memory write of the device's global timestamp value into a
/// command list.
///
/// @details
/// - The application must ensure the events are accessible by the device on
/// which the command list was created.
/// - The timestamp frequency can be queried from
/// ::ze_device_properties_t.timerResolution.
/// - The number of valid bits in the timestamp value can be queried from
/// ::ze_device_properties_t.timestampValidBits.
/// - The application must ensure the memory pointed to by dstptr is
/// accessible by the device on which the command list was created.
/// - The application must ensure the command list and events were created,
/// and the memory was allocated, on the same context.
/// - The application must **not** call this function from simultaneous
/// threads with the same command list handle.
/// - The implementation of this function should be lock-free.
