Merge branch 'lukas/asn1/ber_encode_nif/OTP-9441' into major
* lukas/asn1/ber_encode_nif/OTP-9441:
Update to use enif_alloc instead of malloc
Make performance code more generic and migrate per/ber NBAP perormance suites to use the generic code
Update code genaration to call nif/erlang depending on what is configured
Remove export_all and only export is_nif_loadable
Add documentation for ber encode nif optmization
Fix bug in counting length of empty composite types
Fix bug where composite types with more then one element would be encoded in reverse
Add pubkey performance tests
Update ber encode nif to use a linked list memry buffer
Create a nif for ber encode
Extract generic is_nif_loadable function from decode
