Makefile.dist: delete

It had shorthand aliases to launch `./configure` and
`./configure --with-openssl`. The former hasn't worked for a long while
because of missing TLS.

Its `ca-bundle` and `ca-firefox` targets have been broken for 2.5 years
till recently. These targets also exist in `./configure` and have been
working all along.

Also:
- cmake: add support `curl-ca-bundle` and `curl-ca-firefox` targets.
- tests/testcurl.pl: drop obsolete build logic.

Closes #16094
