virtual_nvmem: add virtual nvmem factory_config support

Add support for reading the factory config from virtual nvmem. This
change uses the same index as ti50 --index=0x3fff06. There are two
indices that are reserved, but not implemented for cr50. This change
registers a REGISTER_DEPRECATED_CONFIG for VIRTUAL_NV_INDEX_RMA_BYTES
and VIRTUAL_NV_INDEX_WV_UDS_BYTES.

BUG=b:278118981,b:214065944
TEST=manual
Set the factory config to 0xface
Read the config from virtual nvmem
tpm_manager_client read_space --index=0x3fff06 --file=/tmp/contents
INFO tpm_manager_client: [main.cc(595)] ...
  result: NVRAM_RESULT_SUCCESS
  data: CEFA000000000000
}

RMA_BYTES and the WV_UDS_BYTES index still return nothing
tpm_manager_client read_space --index=0x3fff04 --file=/tmp/contents
INFO tpm_manager_client: [main.cc(595)] ...
