Fix #69882: OpenSSL error "key values mismatch" after openssl_pkcs12_read with extra certs

The "key values mismatch" error is triggered in openssl_pkcs12_read by
PKCS12_parse, because it uses X509_check_private_key to separate main
certificate (which corresponds to private key) from extra certificates.
Extra certificates usually comes first (p12 contents are reversed as
stack) and X509_check_private_key triggers X509_R_KEY_VALUES_MISMATCH
error.
The fix pops "key values mismatch" error from OpenSSL error stack for
each extra certificate if there are any.

Make convert_to_* safe with rc>1

This only involves switching zval_dtor to zval_ptr_dtor for arrays
and making the convert_to_object for arrays a bit more generic.

All the other changes outside zend_operators.c just make use of
this new ability (use COPY instead of DUP).

What's still missing: Proper references handling. I've seen many
convert_to* calls that will break when a reference is used.

Also fixes bug #69788.
