KEYS: trusted_tpm1: Move private functionality out of public header

Move functionality used only by trusted_tpm1.c out of the public header
<keys/trusted_tpm.h>.  Specifically, change the exported functions into
static functions, since they are not used outside trusted_tpm1.c, and
move various other definitions and inline functions to trusted_tpm1.c.
