ANDROID: GKI: x86: Update ABI and symbol list after pvMMIO changes

Commit "ANDROID: x86/paravirt: Add pv_mmio_ops" changed the x86 ABI:
extended the 'paravirt_patch_template' struct with new fields, and
correspondingly changed the 'pv_ops' global variable value.

So update x86 ABI accordingly, via:

  tools/bazel run //common:kernel_x86_64_abi_update

Additionally update the symbol list for the Cuttlefish kernel
(virtual_device_x86_64): add the 'pv_ops' symbol to it, to fix the
build error:

  These symbols are missing from the symbol list and are not available at runtime for unsigned modules:
    pv_ops required by ['goldfish_battery.ko', 'mt76.ko', 'mt76x02-lib.ko']

Note that even though the aforementioned commit only changes the MMIO
accessors operation for pKVM guest kernels (i.e. Microdroid kernels),
not for regular Android kernels including Cuttlefish (since kernel will
detect at runtime that it is not a pKVM guest and thus will patch the
MMIO accessors to make them work exactly like before that commit), it
still makes them depend on the 'pv_ops' symbol at build time.
