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.

pci: extend MSI interrupt vector number to 32 bits

Also increase MSI message data size to 32 bits according to PCIe spec.

Remove 0xff check for MSI interrupts because it is potentially valid
interrupt vector number. Reject 0xff only for legacy pin interrupts.

- MSI-X supports up to 2048 interrupts per device that do not fit to
`uint8`.

- Non-x86 systems may use separate interrupt vector ranges for
hard-wired interrupts and MSI interrupts so `uint8` is not enough to
represent all of them.

CIDs 1162783 & 1162784: out-of-bounds access & write in MSI.

* The number of IO vectors is not 256 on x86, but rather 224 as set by
NUM_IO_VECTORS in "arch_int.h".
* Jessicah mentioned hearing about MSI crashes before, but that was a
few weeks ago.
* These were the only CIDs in the MSI code.

x86[_64]: Support assigning MSI IRQs to arbitrary CPU

MSI: Use the effective APIC id of the boot CPU for the address destination.

* This should only affect systems where the CPU ids aren't sequential (mostly
non Intel).
* Fixes #9807.

Compile remaining x86 bits for x86_64.

The IOAPIC and IRQ routing code now gets compiled for x86_64, though
they won't be used yet as there is no ACPI support currently.

Compile msi.cpp for x86_64.

Needed to link the PCI module, not enabling it yet though, I'm not
sure whether everything needed for it is in place yet.

Fix and add copyright year spotted by Urias.

* Introduce {reserve|allocate|free}_io_interrupt_vectors() that can generically
be used to mark certain io interrupt vectors as reserved and to allocate from
the still free ones. It is a kernel private API for now though.
* Make the MSI code use that functionality instead of implementing its own which
slims it down considerably and also removes quite a bit of hardcoded knowledge
about the interrupt layout that didn't really belong there.
* Mark the various in-use interrupts as reserved from the components that
actually know about them (PIC, IO-APIC, SMP, APIC timer and interrupt setup).

* When initializing MSI support, don't assume a single 24 entry IO-APIC. Instead
mark the ISA interrupts as unusable and then use ioapic_is_interrupt_available
to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
not used, this will simply always return false, leaving all vectors free for
MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external
routing anymore).

* Add code to allocate and free interrupt vectors for message signaled
interrupts (MSI).
* Add the remaining IDT entries and redirection functions in the interrupt code.
* Make the PIC end_of_interrupt() return a result to indicate whether the vector
was handled by this PIC. If it isn't we now issue a apic_end_of_interrupt()
in the assumption of apic local interrupt, MSI or IPI. This also removes
the need for the gUsingIOAPIC global and doing manual apic_end_of_interrupt()
calls in the SMP and timer code.
