EVP_PKEY_CTX_set_ec_ functions were only available when EC was enabled
('no-ec' not configured). However, that makes it impossible to use
these functions with an engine or a provider that happens to implement
EC_KEY. This change solves that problem by shuffling these functions
to more appropriate places.
Partially fixes#13550
squash! EVP_PKEY & EC_KEY: Make EC EVP_PKEY_CTX parameter ctrls / setters more available
By consequence, there are a number of places where we can remove the
check of OPENSSL_NO_EC. This requires some re-arrangements of
internal tables to translate between numeric identities and names.
