TA dev kit: add support for TA encryption

Add CFG_ENCRYPT_TA as TA build time configuration option to enable
encryption of TA using encryption key provided via TA_ENC_KEY build
time option. The default value of TA_ENC_KEY is derived from 16 zero
bytes default hardware unique key.

Also rename scripts/sign.py to scripts/sign_encrypt.py to reflect
optional encryption support along with signing of TAs.
