curl: support embedding a CA bundle
Add the ability to embed a CA bundle into the curl binary. It is used
when no other runtime or build-time option set one.

This helps curl-for-win macOS and Linux builds to run standalone, and
also helps Windows builds to avoid picking up the CA bundle from an
arbitrary (possibly world-writable) location (though this behaviour is
not currently disablable).

Usage:
- cmake: `-DCURL_CA_EMBED=/path/to/curl-ca-bundle.crt`
- autotools: `--with-ca-embed=/path/to/curl-ca-bundle.crt`
- Makefile.mk: `CURL_CA_EMBED=/path/to/curl-ca-bundle.crt`

Also add new command-line option `--dump-ca-embed` to dump the embedded
CA bundle to standard output.

Closes #14059

--proxy-capath

Same as --capath but used in HTTPS proxy context.

Use the specified certificate directory to verify the proxy. Multiple paths can be provided by separated with colon (:) (e.g. path1:path2:path3). The certificates must be in PEM format, and if curl is built against OpenSSL, the directory must have been processed using the c_rehash utility supplied with OpenSSL. Using --proxy-capath can allow OpenSSL-powered curl to make SSL-connections much more efficiently than using --proxy-cacert if the --proxy-cacert file contains many CA certificates.

If this option is set, the default capath value is ignored.
