wolfcrypt/src/aes.c: enforce AES-XTS K1!=K2 constraint in wc_AesXtsSetKeyNoInit() unless WC_AES_XTS_ALLOW_DUPLICATE_KEYS and !HAVE_FIPS: tests/api/test_aes.c: add negative tests to test_wc_AesXtsSetKey() for K1==K2; wolfcrypt/test/test.c: fix keys in aes_xts_128_inplace_test() and aes_xts_192_inplace_test() so that K1!=K2, update test vectors, and remove associated !HAVE_FIPS gating; linuxkm/lkcapi_aes_glue.c: synchronize aes_xts_128_test() test of ciphertext stealing in-place with wolfcrypt/test/test.c. wrapper/rust/wolfssl-wolfcrypt/src/aes.rs: synchronize XTS streaming test with wolfcrypt/test/test.c. linuxkm/: refactor self-test sensing with version-gated setup in linuxkm_wc_port.h and refactored gates in lkcapi_glue.c.
