* build(meson): bump minimum version to 0.62.0
This allows making some minor cleanups
* test(meson): fix SSLClientServerTest.* tests with OpenSSL 3.2.0
Since OpenSSL commit
<342e3652c7>,
the default X.509 certificate format generated with the `openssl req`
command has been changed to X.509 v3 from X.509 v1.
For some reason, this change breaks cpp-httplib's SSLClientServerTest.*
tests.
To fix the test failures, this patch passes the '-x509v1' flag instead
of '-x509' when OpenSSL 3.2.0 or newer is detected. To detect the
version of a command line utility, Meson 0.62.0 or later is required.
Fixes <https://github.com/yhirose/cpp-httplib/issues/1798>, but only for
the Meson build system.
