Introduce low-voltage detection driver support on RX130
The voltage detection circuit (LVD) monitors the voltage level input to the VCC or external pin using a program.
Upon detecting a voltage level transition (either upward or downward) past the configured threshold, the system can generate a reset or an interrupt, enabling appropriate protective or recovery actions.

Update commit ID to add LVD HAL support for LVD
