Automated replacement with
```
git ls-files -z wolfcrypt/src/port/ IDE/ | xargs -0 pcre2grep -l '[^_]AES_BLOCK_SIZE' | xargs sed --regexp-extended --in-place 's/([^_])AES_BLOCK_SIZE/\1WC_AES_BLOCK_SIZE/g'
```
Checked for mis-transformations with
```
git ls-files -z | xargs -0 pcre2grep '[^-[()+*/[:space:]]WC_AES_BLOCK_SIZE' | less
```
Checked for residual hits with
```
git ls-files -z | xargs -0 pcre2grep '[^_]AES_BLOCK_SIZE' | less
```
Deliberately excluded:
* ChangeLog.md -- do not alter history.
* doc/ -- do not confuse documentation with newly prefixed macro, because AES_BLOCK_SIZE is available unless -DOPENSSL_COEXIST.
* tests/api.c -- the unit tests deliberately use compatibility names, and are not compatible with -DOPENSSL_COEXIST.
* wrapper/CSharp/wolfSSL_CSharp/wolfCrypt.cs -- false positive hits on C# names.
* wrapper/CSharp/wolfCrypt-Test/wolfCrypt-Test.cs -- false positive hits on C# names.
* reference in wolfssl/wolfcrypt/aes.h that defines AES_BLOCK_SIZE when -UOPENSSL_COEXIST.
* reference in wolfssl/wolfcrypt/settings.h that defines WC_AES_BLOCK_SIZE for old FIPS when -UWC_AES_BLOCK_SIZE.
