feat(spmd): copy tos_fw_config in secure region

The tos_fw_config is currently loaded into memory by BL2 and
consumed by SPMD (part of BL31) and BL32 firmwares. This does
not work in RME-enabled systems as BL31 uses the root PAS memory
and does not trust secure PAS memory.

A first attempt was made to map the TOS_FW_CONFIG region as root PAS,
and then to remap to secure PAS after SPMD consumption, but this was
not suitable for RME systems where memory encryption is enabled.

This can be solved by copying the TOS FW config (SPMC manifest) from
the Root PAS region to the Secure PAS region so that BL32 can consume
it.
