[bus-pci] Split PCI bus driver for user and kernel implementations

This splits the two definitions of the PCI bus driver (kernel and user
space PCI) into separately named drivers that are included in the
configurations which need them. The driver using user space PCI support
is called 'bus-pci' and is included on all x86_64 and RISC-V
configurations as well as the vim3 and pkvm boards. The driver using
kernel PCI support is called 'bus-kpci' and is used on qemu-arm64.

Previously, the bus was always called 'bus-pci' and its definition was
determined by the platform_enable_user_pci GN argument.

This change modifies the 'arm64' and 'qemu-arm64' boards, both of which
are used in qemu to emulate an arm64 device.
