We use dh2048_ffdhe2048.pem file (DH 2048 bits) instead of dh1024.pem file in
both non-FIPS and FIPS cases. Because the following command fails to generate
the pem file with 1024 bits. And the OpenSSL FIPS 140-2 security policy
document explains the DH public keys are allowed from 2048 bits.[1]

```
$ OPENSSL_CONF=/home/jaruga/.local/openssl-3.3.0-dev-fips-debug-1aa08644ec/ssl/openssl_fips.cnf \
  /home/jaruga/.local/openssl-3.3.0-dev-fips-debug-1aa08644ec/bin/openssl \
  dhparam -out dh1024.pem 1024
Generating DH parameters, 1024 bit long safe prime
dhparam: Generating DH key parameters failed
```

The dh2048_ffdhe2048.pem file was created by the following command with the
OpenSSL FIPS configuration file. The logic to generate the DH pem file is
different between non-FIPS and FIPS cases. In FIPS, it seems that the command
always returns the text defined as ffdhe2048 in the FFDHE groups in RFC 7919
unlike non-FIPS.[2]

As the generated pem file is a normal and valid PKCS#3-style group parameter, we
use the file for the non-FIPS case too.

```
$ OPENSSL_CONF=/home/jaruga/.local/openssl-3.3.0-dev-fips-debug-1aa08644ec/ssl/openssl_fips.cnf \
  /home/jaruga/.local/openssl-3.3.0-dev-fips-debug-1aa08644ec/bin/openssl \
  dhparam -out dh2048_ffdhe2048.pem 2048
```

Note that the hard-coded PEM-encoded string in the `test_DHparams` is
intentional to avoid modifying the content unintentionally.

test/openssl/fixtures/ssl/openssl_fips.cnf.tmpl:

I referred to the following document for the openssl config file for FIPS mode.
<https://www.openssl.org/docs/manmaster/man7/fips_module.html>
- Making all applications use the FIPS module by default

It seems that the `.include` syntax only requires the absolute path.
So, the placeholder OPENSSL_DIR in the template file is replaced with the
actual OpenSSL directory.

.github/workflows/test.yml:

The `TEST_RUBY_OPENSSL_FIPS_ENABLED` environment variable is set
in the FIPS mode CI case. It can be used in the unit tests.

https://github.com/ruby/openssl/commit/18b017218c

The behavior of EVP_PKEY_public_check changed between OpenSSL 1.1.1
and 3.0 so that it no longer validates the private key. Instead, private
keys can be validated through EVP_PKEY_private_check and
EVP_PKEY_pairwise_check.

[ky: simplified condition to use either EVP_PKEY_check() or
EVP_PKEY_public_check().]

Import the master branch of ruby/openssl for preparing to release openssl-2.2.0

OpenSSL 1.1.1 rejects some shorter keys, which caused some failures of
`make test-all TESTS=openssl`.
