f6d9fb10b1 drivers/interrupt_controller/loapic.h: add IPI support
Add a simple inline function and some definitions to faciliate
inter-processor interrupts for SMP initialization/synchronization.

a981f51fe6 arch/x86: drivers/loapic_intr.c: move local APIC initialization
In the general case, the local APIC can't be treated as a normal device
with a single boot-time initialization - on SMP systems, each CPU must
initialize its own. Hence the initialization proper is separated from
the device-driver initialization, and said initialization is called
from the early startup-assembly code when appropriate.

ee525c2597 arch/x86: inline x2APIC EOI
From the Jailhouse days, this has been a function call. That's silly.
We now inline the EOI in the ISR when in x2APIC mode. Also clean up
z_irq_controller_eoi(), so it now uses the inline macros.

Also, we now enable x2APIC on up_squared by default.

Fixes: #17133

cb412df725 x86: remove code for interrupt forwarding bug
This only applied to quark_se, so removing it.

0325a3d972 arch/x86: eliminate include/arch/x86/irq_controller.h
The MVIC is no longer supported, and only the APIC-based interrupt
subsystem remains. Thus this layer of indirection is unnecessary.

This also corrects an oversight left over from the Jailhouse x2APIC
implementation affecting EOI delivery for direct ISRs only.

c384c6685e arch/x86: move include/arch/x86/sys_io.h to ia32/sys_io.h
These inlines currently only apply to IA32, so place accordingly.
Minor changes to direct and indirect users of the file for ordering.
