915f4ac3c7 drivers/interrupt_controller: Get the IOAPIC RTEs dynamically 
The fixed number of 24 RTEs is a legacy thing, and long gone by now.
IOAPICs expose the maximum number of RTEs they have via the version
register, so let's use it.

This avoids to manually tweak a Kconfig option (which is now removed)
and fixes the RTE number for all x86 targets relevantly.

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

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.
