drivers: gpio_cc32xx: disable interrupts before changing interrupt type

Disabling gpio interrupts on the pin prior to changing its interrupt
type to level-based helps prevent spurious interrupts that would be
otherwise observed, if gpio interrupts were originally enabled when
gpio_cc32xx_pin_interrupt_configure() is invoked.

Fixes #22847
