The existing names such as EVP_PKEY_param_fromdata_settable were a bit
confusing since the 'param' referred to key params not OSSL_PARAM. To simplify
the interface a 'selection' parameter will be passed instead. The
changes are:
(1) EVP_PKEY_fromdata_init() replaces both EVP_PKEY_key_fromdata_init() and EVP_PKEY_param_fromdata_init().
(2) EVP_PKEY_fromdata() has an additional selection parameter.
(3) EVP_PKEY_fromdata_settable() replaces EVP_PKEY_key_fromdata_settable() and EVP_PKEY_param_fromdata_settable().
EVP_PKEY_fromdata_settable() also uses a selection parameter.
Fixes #12989
