drivers: interrupt_controller: stm32: Generate irq_table and isr from dt

This change takes advantage of line information coming from new properties
to simplify exti_irq_table definition and isr routing related code.

All __stm32_exti_isr_x routing functions are removed and instead,
stm32_exti_isr is now taking a exti_range structure which provides,
for each irq, start line and range length.
This argument is provided by IRQ_CONNECT macro instead of previous
dev info (which is constant and doesn't need to be provided as argument).

line_range_x variables are generated at driver init thanks to a
mix of dt magic and runtime implementation:
DT_FOREACH_PROP_ELEM iterates over each irq line (counted as
interrupt-names property) call a macro which instantiates populated
line_range_x variables, and calls IRQ_CONNECT for each IRQ.
Additionally, at each iteration stm32_fill_irq_table() is called to
fill exti_irq_table.

Since not required anymore, Kconfig symbols EXTI_STM32_EXTIX_Y_IRQ_PRI
are removed. IRQ prio is now supposed to be configured in device tree.
