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.

ngtcp2: support latest QUIC TLS RFC9001

QUIC Transport Parameters Extension has been changed between draft-29
and latest RFC9001. Most notably, its identifier has been updated from
0xffa5 to 0x0039. The version is selected through the QUIC TLS library
via the legacy codepoint.

Disable the usage of legacy codepoint in curl to switch to latest
RFC9001. This is required to be able to keep up with latest QUIC
implementations.

tool_operate: a failed etag save now only fails that transfer

When failing to create the output file for saving an etag, only fail
that particular single transfer and allow others to follow.

In a serial transfer setup, if no transfer at all is done due to them
all being skipped because of this error, curl will output an error
message and return exit code 26.

Added test 369 and 370 to verify.
