0a4270d732 Change the compatibility API to inline functions
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.

b87b719467 Remove old values of curve encodings
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.

7a894f2142 Move backward compatibility aliases to their own header
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.
