TinyCrypt SSL: Declare EC-related TLS RFC constants in SSL namespace

mbedtls/ecp.h defines constants

   MBEDTLS_ECP_PF_UNCOMPRESSED
   MBEDTLS_ECP_PF_COMPRESSED
   MBEDTLS_ECP_TLS_NAMED_CURVE

which regard the encoding of elliptic curves and curve point formats in TLS.
As such, they should be defined in the SSL namespace. Asides, this will help
replacing the legacy ECC crypto by alternative ECC implementations.
