feat(php-shim): align fwrite/touch2/PHP_OS_FAMILY/PHP_URL_SCHEME with PHP

Adjust fwrite to return int|false equivalent (Option<i64>), add touch2
with mtime, implement PHP_OS_FAMILY via std::env::consts::OS, and swap
the PHP_URL_HOST placeholders for the now-available PHP_URL_SCHEME.
Wire these into locker, filesystem, platform, and remote_filesystem.
