  Fix data type of SM2 EC_PUB_X/Y params

The provider's gettable-params list advertised types that didn't match
what the getter implementation supported, so fetching either coordinate
tripped "incompatible type".  Nothing in-tree was asking; the follow-up
commit adds a test that detects the problem.

  Log Message:
  -----------
  Expand and refactor test_evp_extra2

The "expand" part adds a algorithm-independent probe that walks every
gettable OSSL_PARAM of an EVP_PKEY in two passes -- first a size query,
then a real fetch.  This is exercised for each algorithm.  In the SM2
case it catches the gettable-params/getter type mismatch fixed in the
preceding commit: reverting that commit trips the probe for SM2.

The "refactor" part replaces the per-algorithm test code with a single
PKEY_TEST_SPEC table of (name, optional prefab DER, optional keygen
params), driven through pkey_from_spec().  The key-selection and
gettable tests no longer involve any algorithm-specific code.
