Restrict range of buffer_length on all platforms to INT_MAX

This has only been done for Windows systems so far, and there was a
TODO comment about looping for larger values; that appears to be
overkill, though, since 2 million bytes should be sufficient for all
use cases, and if there is really the need for more, users can still
loop manually. Anyhow, checking the range upfront on all platforms
is clearer then silently casting to `int`.

We split the error message for the least possible BC break.

Closes GH-9126.

Fixed bug #81502

Allow $tag to be null. This is the value that openssl_encrypt()
sets it to for non-AEAD ciphers, so we should also accept this
as an input to openssl_decrypt().

Prior to PHP 8.1, null was accepted in weak mode due to the special
treatment of null arguments to internal functions.

Switch default PKCS7/CMS cipher to AES-128-CBC

Switch default cipher for openssl_pkcs7_encrypt() and
openssl_cms_encrypt() from RC2-40 to AES-128-CBC.

The RC2-40 cipher is considered insecure and is not loaded by
default in OpenSSL 3, which means that these functions will
always fail with default arguments.

As the used algorithm is embedded in the result (which makes this
different from the openssl_encrypt() case) changing the default
algorithm should be safe.

Closes GH-7357.

Use param API to create RSA key

A caveat here is that when using the high-level API, OpenSSL 3
requires that if the prime factors are set, the CRT parameters
are also set. See https://github.com/openssl/openssl/issues/16271.

As such, add CRT parameters to the manual construction test.

This fixes the last deprecation warnings in openssl.c, but there
are more elsewhere.

Switch manual DSA key generation to param API

This is very similar to the DH case, with the primary difference
that priv_key is ignored if pub_key is not given, rather than
generating pub_key from priv_key. Would be nice if these worked
the same (in which case we should probably also unify the keygen
for FFC algorithms, as it's very similar).

Store whether pkey object contains private key

Rather than querying whether the EVP_PKEY contains private key
information, determine this at time of construction and store it
in the PHP object.

OpenSSL doesn't provide an API for this purpose, and seems
somewhat reluctant to add one, see
https://github.com/openssl/openssl/issues/9467.

To avoid using deprecated low-level APIs to determine whether
something is a private key ourselves, remember it at the point
of construction.
