This patch changes the compatibility API defined in crypto_compat.h
to static inline functions as the previous macro definitions were
causing issues for the C pre-processor when included in projects
which need to redefine the PSA function names. Making it static
inline function solves this problem neatly and also modern compilers
do a good job at inlining the function which makes the need for making
it a macro redundant.

Remove the values of curve encodings that are based on the TLS registry
and include the curve size, keeping only the new encoding that merely
encodes a curve family in 8 bits.
Keep the old constant names as aliases for the new values and
deprecate the old names.
Move backward compatibility aliases to a separate header. Reserve
crypto_extra.h for implementation-specific extensions that we intend
to keep supporting.
This is better documentation for users. New users should simply ignore
backward compatibility aliases, and old users can look at
crypto_compat.h to see what is deprecated without bothering about new
features appearing in crypto_extra.h.
This facilitates maintenance because scripts such as
generate_psa_constants that want to ignore backward compability
aliases can simply exclude crypto_compat.h from their parsing.
