kernel/int: consolidate interrupt vector number to `int32`

This is no-op for 32 bit platforms because `int32` is defined as `long` there.

Change interrupt vector number from 64 bits to 32 bits for 64 bit platforms.

kernel/int: Allow arch_int_assign_to_cpu to make its own decisions.

For now this is used on RISCV64 to indicate that interrupts will always
be on CPU 0. However, in the future, some architectures may want
or require interrupts to be "steered" in various ways, and this
also paves the way for that.
