Unify types of PHP_VERSION and friends on Windows

For `phpize` builds, all three version variables are numbers, but for
`buildconf` builds, all are strings.  This can yield surprising results
when extensions create their `PHP_VERSION_ID` like

10000 * PHP_VERSION + 100 * PHP_MINOR_VERSION + PHP_RELEASE_VERSION

Since `phpize` builds are way more common for external extensions
nowadays, we change the types for `buildconf` builds.

Closes phpGH-16247.
