hw/i386/microvm: Explicitly select ACPI_PCI

With a microvm-only build based on a custom device config,
we get a link failure due to undefined reference to
build_pci_host_bridge_osc_method() which is defined in hw/acpi/pci.c and
whose compilation depends on CONFIG_ACPI_PCI. Although CONFIG_ACPI
and CONFIG_PCI are set with such configuration, implied CONFIG_ACPI_PCI
in config PCI_EXPRESS_GENERIC_BRIDGE is not selected as expected.

It Looks like CONFIG_ACPI_PCI must be enforced and this patch selects
CONFIG_ACPI_PCI in MICROVM config directly as done for PC config.

Reproducer:

../configure \
 --without-default-features \
 --target-list=x86_64-softmmu \
 --enable-kvm --disable-tcg \
 --enable-pixman \
 --enable-vnc \
 --audio-drv-list="" \
 --without-default-devices \
 --with-devices-x86_64=microvm \
 --enable-vhost-user

with configs/devices/x86_64-softmmu/microvm.mak:
CONFIG_PCI_DEVICES=n

CONFIG_MICROVM=y

CONFIG_VIRTIO_BLK=y
CONFIG_VIRTIO_SERIAL=y
CONFIG_VIRTIO_INPUT=y
CONFIG_VIRTIO_INPUT_HOST=y

CONFIG_VIRTIO_RNG=y
CONFIG_VIRTIO_CRYPTO=y
CONFIG_VIRTIO_BALLOON=y
