Allow for FIPS builds without ED25519 & MD5

[lealem47]

Goes along with wolfSSL/wolfssl#11144

[Copilot]

Pull request overview

This PR improves wolfCLU’s behavior (and test suite robustness) when building against wolfSSL configurations that omit MD5 and/or ED25519 (e.g., FIPS-focused builds), by returning NOT_COMPILED_IN with clearer messages and having tests skip appropriately instead of failing.

Changes:

• Added a shared Python test helper to detect NOT_COMPILED_IN via wolfCLU’s "Error returned: -174." reporting and updated select tests to skipTest() when algorithms are not present.
• Updated MD5-related setup paths (hash/dgst/bench/HMAC) to return NOT_COMPILED_IN and emit consistent “not compiled in” errors when NO_MD5 is enabled.
• Updated ED25519 verify/sign codepaths to return NOT_COMPILED_IN when ED25519 support is not compiled in.

File	Description
tests/wolfclu_test.py	Adds NOT_COMPILED_IN constant and not_compiled_in() helper for skipping optional-algorithm tests.
tests/hash/hash-test.py	Skips MD5 hash test when MD5 isn’t compiled into wolfSSL.
tests/genkey_sign_ver/genkey-sign-ver-test.py	Skips optional key-type generation when wolfSSL reports NOT_COMPILED_IN (e.g., ED25519 omitted).
tests/bench/bench-test.py	Skips MD5 benchmark when MD5 isn’t compiled into wolfSSL.
src/tools/clu_funcs.c	Adds NO_MD5 handling in HMAC hash selection for MD5.
src/sign-verify/clu_verify.c	Returns/logs NOT_COMPILED_IN when ED25519 verify is unavailable; silences unused params in stubs.
src/sign-verify/clu_sign.c	Returns NOT_COMPILED_IN for ED25519 sign when unavailable; silences unused params in stub.
src/sign-verify/clu_dgst_setup.c	Returns/logs NOT_COMPILED_IN for -md5 selection when NO_MD5.
src/hash/clu_hash_setup.c	Returns/logs NOT_COMPILED_IN for md5 shortcut when NO_MD5.
src/benchmark/clu_bench_setup.c	Ensures --md5 is recognized even under NO_MD5 so a targeted NOT_COMPILED_IN error can be returned.
