lib1587: fix gcc -Wconversion with LibreSSL on Windows, test in CI

By exposing and reusing existing custom type via `vtls/openss.h`.

Also:
- GHA/curl-for-win: test in CI by enabling building tests.
  Cost is 45s per job, so limit it to the gcc job.

Seen with Windows x64 gcc (not tested in CI prior to this patch):
```
tests/libtest/lib1587.c:50:7: error: conversion from 'opt1587' {aka 'long long unsigned int'} to 'long int' may change value [-Werror=conversion]
   50 |       SSL_CTX_set_options(info->internals, opts);
      |       ^~~~~~~~~~~~~~~~~~~
