Arun Menon a8aa1b220c hw/tpm: Add support for VM migration with TPM CRB chunking
- Add subsection in VMState for TPM CRB with the newly introduced
  command and response buffer GByteArrays, along with a needed callback,
  so that newer QEMU only sends the buffers if it is necessary.
- Implement a migration blocker to prevent migration of the VM if the
  user manually enables chunking capability, cap-chunk, but the machine
  type does not support it, using a new hw_compat property called
  allow_chunk_migration.
- Add a post_load_errp hook so that during a migration, the buffers are
  validated before destination VM is started.
