Add option to invoke QEMU with a PVM template

Add -T command line option to aarch64/run_qemu.sh which invokes QEMU
with a given file as a PVM template.

It will automatically determine the address at which the file will be
placed in memory. This is based on the fixed QEMU memory layout:
    kernel | initrd | dtb | template

It will run QEMU first to dump its DTB and then overlay it with a node
specifying the address and size of the template before running QEMU
properly.

Bug: 171309087
Test: run_qemu.sh with a script:
      hexdump -C /proc/device-tree/pkvm_template@*/reg
