ecp: Fix binary compatibility with group ID

We naturally added the new Curve448 ECP group ID in alphabetical order in
the mbedtls_ecp_group_id enum. However, this causes binary incompatibility
issues as previous binaries will use values for groups that now have a
different meaning. For example, MBEDTLS_ECP_DP_SECP192K1, old value 10,
would mean Curve448 (MBEDTLS_ECP_DP_CURVE448) and the wrong group ID used.

Fix the binary compatibility issue by adding new enum entries to the end of
the enum, even though this isn't so great for readbility as the list is no
longer in alphabetical order. However, the list wasn't perfectly in
alphabetical order before anyway.
