Add a software crypto-callback device (wc_swdev) that lets the wolfcrypt test suite run under WOLF_CRYPTO_CB_ONLY_* flags without per-test devId plumbing. The bundle is a separately-compiled second copy of wolfcrypt (software implementations enabled, WOLF_CRYPTO_CB_ONLY_* stripped) linked into testwolfcrypt as a single relocatable object; every symbol is demoted to local via objcopy --keep-global-symbol except wc_SwDev_Callback, so there is no collision with the main libwolfssl. A find callback routes unbound operations (devId == INVALID_DEVID) to the swdev while letting real device IDs pass through. wc_SwDev_Init / wc_SwDev_Cleanup hooks are wired into wolfcrypt/test/test.c. cryptocb_test's WOLF_CRYPTO_CB_FIND and WOLF_CRYPTO_CB_ONLY_RSA blocks are gated off under WOLFSSL_SWDEV. Enable via --enable-swdev (requires --enable-cryptocb).
