To better reflect its purpose, move the `PIN_CFG_VARIABLE` macro beside `RZG2L_SINGLE_PIN` and rename it to `RZG2L_CFG_VARIABLE`. Additionally, introduce new macros for packing variable port configurations: - `RZG2L_GPIO_PORT_PACK_VARIABLE(n, a)`: Combines `RZG2L_CFG_VARIABLE` with `RZG2L_GPIO_PORT_PACK` to handle variable pin configurations for a packed port. - `RZG2L_GPIO_PORT_SPARSE_PACK_VARIABLE(m, a)`: Combines `RZG2L_CFG_VARIABLE` with `RZG2L_GPIO_PORT_SPARSE_PACK` to handle variable pin configurations for a sparse port. Due to the above change the configuration macros have been reorganized as follows: - Shift the bit positions of `PIN_CFG_NOGPIO_INT`, `PIN_CFG_NOD`, `PIN_CFG_SMT`, `PIN_CFG_ELC`, and `PIN_CFG_IOLH_RZV2H` down by one to accommodate the removal of `PIN_CFG_VARIABLE`.
