Tomas Mraz ddf0d149e2 Rename EVP_PKEY_get0_first_alg_name to EVP_PKEY_get0_type_name 
We use type elsewhere and documenting the 'first' in the
name of the call is a little bit superfluous making the
name too mouthful.

Also rename EVP_PKEY_typenames_do_all to
EVP_PKEY_type_names_do_all to keep the words separated by
underscore.

Fixes #14701
