rename WOLFSSL_MAX_RSA_BITS to WC_MAX_RSA_BITS, and move its setup from wolfssl/internal.h to wolfssl/wolfcrypt/asn.h, preceding setup for WC_MAX_CERT_VERIFY_SZ.
configure.ac: restore opensslextra-linuxkm assertion, with a twist: "--enable-opensslextra with --enable-linuxkm-pie and without --enable-cryptonly is incompatible with --enable-linuxkm."
wolfcrypt/src/asn.c: fix trailing comma in enum.
wolfcrypt/src/port/arm/armv8-aes.c: fix wc_AesCcmEncrypt() and wc_AesCcmDecrypt() for test_wolfssl_EVP_aes_ccm_zeroLen().
No functional changes.
Several compat symbols that were formerly enums are now macros.
All library source is refactored to use only native symbols in all code gated in with --enable-all-crypto --enable-opensslextra.
wolfcrypt/test/test.c is similarly refactored to use only native symbols.
examples/ and tests/ are unmodified except for header setup to disable OPENSSL_COEXIST and TEST_OPENSSL_COEXIST.

* Consolidate the USE_WINDOWS_API to a single place.
* Expand the `WOLFSSL_NOT_WINDOWS_API` improvement for intrinsics and word sizes.
* Fix for macro variadic `...` when no variables are used (some compilers like Watcom C have issue with this).
* Fix for Watcom C compiler "long long" -> "__int64".
* Fix a couple of minor cast warnings reported from VS.
wolfcrypt/src/port/arm/armv8-aes.c: in the WOLFSSL_ARMASM_NO_HW_CRYPTO version of wc_AesSetKey(), copy the supplied userKey to a properly aligned buffer if necessary before calling AES_set_encrypt_key();
src/dtls13.c: in Dtls13GetRnMask(), if defined(WOLFSSL_LINUXKM)), return retval of wc_AesEncryptDirect();
wolfcrypt/src/misc.c: add readUnalignedWord32(), writeUnalignedWord32(), readUnalignedWords32(), and writeUnalignedWords32();
wolfcrypt/src/siphash.c: use readUnalignedWord64(), readUnalignedWord32(), and writeUnalignedWord64(), to avoid unaligned access faults, and fix cast in byte-reversing version of GET_U32().
