Only calculate the tplink emeter values once per update cycle (#115587)

Browse Source 
The sensor platform has to read the native_value multiple times
during the state write cycle which means the integration calculated
the value multiple times. Switch to using _attr_native_value to
ensure the calculations in the library are only done once per
state write.

To demonstrate this issue,
+        _LOGGER.warning("Fetch name value for %s", self.entity_id)
was added to `def native_value`:
