[PATCH 6.18.y 1/5] KVM: x86: Move IRQ-related helper declarations from kvm_host.h => irq.h

[Sasha Levin <sashal@kernel.org>]

From: Sean Christopherson <seanjc@google.com>

[ Upstream commit 0bdd2d6d7328a7debcf138a7d6ef95d01a26b1b8 ]

Move the function declaration for APIs to get/query pending IRQs from
kvm_host.h to irq.h, as the APIs are only used by KVM x86 code.

No functional change intended.
