Impact: fix rare crash on 32-bit
The 32-bit APIC drivers had their send_IPI_self vectors set to NULL,
but ioapic_retrigger_irq() depends on it being always set. Fix it.

Impact: 32-bit should use logical version
there are two version: for default_send_IPI_mask_sequence/allbutself
one in ipi.h and one in ipi.c for 32bit
it seems .h version overwrote ipi.c for a while.
restore it so 32 bit could use its old logical version.
also remove dupicated functions in .c

Move all code to arch/x86/kernel/bigsmp_32.c.
With this it ceases to rely on any build-time subarch features.
