gicv3_set_gicv3state() is used by arm_gicv3_common.c in
arm_gicv3_common_realize(). Since we want to restrict
arm_gicv3_cpuif.c to TCG, extract gicv3_set_gicv3state()
to a new file. Add this file to the meson 'specific'
source set, since it needs access to "cpu.h".

The TYPE_ARM_GICV3 device is an emulated one. When using
KVM, it is recommended to use the TYPE_KVM_ARM_GICV3 device
(which uses in-kernel support).
When using --with-devices-FOO, it is possible to build a
binary with a specific set of devices. When this binary is
restricted to KVM accelerator, the TYPE_ARM_GICV3 device is
irrelevant, and it is desirable to remove it from the binary.
Therefore introduce the CONFIG_ARM_GIC_TCG Kconfig selector
which select the files required to have the TYPE_ARM_GICV3
device, but also allowing to de-select this device.
