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
