ArmVirtPkg: PlatformIntelBdsLib: signal ReadyToBoot on direct kernel boot

According to the UEFI spec, EFI_EVENT_GROUP_READY_TO_BOOT "is notified by
the system when the Boot Manager is about to load and execute a boot
option". ArmVirtPkg doesn't do this currently when launching a kernel from
the QEMU command line. OvmfPkg does (see git commit 28a34033ee).

At least two edk2-wide callbacks are worth mentioning:

- OnReadyToBoot() in
  "MdeModulePkg/Universal/Variable/RuntimeDxe/VariableDxe.c" performs
  variable reclaim and (optionally) installs variable usage statistics as
  a vendor config table;

- OnReadyToBoot() in
  "SecurityPkg/Library/DxeImageVerificationLib/DxeImageVerificationLib.c"
  installs the image execution info table if it doesn't exist yet, in
  SecureBoot-enabled builds.
