tests: add Schannel-specific tests and disable unsupported ones

Adds Schannel variants of SSLpinning tests that include the option
--ssl-revoke-best-effort to ignore certificate revocation check
failures which is required due to our custom test CA certificate.

Disable the original variants if the Schannel backend is enabled.

Also skip all IDN tests which are broken while using an msys shell.

This is a step to simplify test exclusions for Windows and MinGW.

runtests: add option -u to error on server unexpectedly alive

case by first making them visible on CI builds as failures.

runtests: add option -u to error on server unexpectedly alive

Let's try to actually handle the server unexpectedly alive
case by first making them visible on CI builds as failures.

This is needed to detect issues with killing of the test
servers completely including nested process chains with
multiple PIDs per test server (including bash and perl).

On Windows/cygwin platforms this is especially helpful with
debugging PID mixups due to cygwin using its own PID space.

CI/azure: improve on flakiness by avoiding libtool wrappers

Install curl binaries into MinGW bin folder and use that
for the tests in order to avoid libtool wrapper binaries.

The libtool wrapper binaries (not scripts) on Windows seem
to be one of the possible causes for the following issues:

1. Process output can be lost in the wrapper process chain.
2. Killing the wrapper process does not kill the actual one.
