How can an extension run some code on its own installation or upgrading?

Place your extension installation / upgrading code into the Setup subfolder.
See for example the Magento_Customer module: https://github.com/magento/magento2/tree/develop/app/code/Magento/Customer/Setup

There are 5 script types: InstallSchema, UpgradeSchema, Recurring, InstallData, UpgradeData

$className = str_replace('_', '\\', $moduleName) . '\Setup';
switch ($type) {
    case 'schema-install':
        $className .= '\InstallSchema';
        $interface = self::SCHEMA_INSTALL;
        break;
    case 'schema-upgrade':
        $className .= '\UpgradeSchema';
        $interface = self::SCHEMA_UPGRADE;
        break;
    case 'schema-recurring':
        $className .= '\Recurring';
        $interface = self::SCHEMA_INSTALL;
        break;
    case 'data-install':
        $className .= '\InstallData';
        $interface = self::DATA_INSTALL;
        break;
    case 'data-upgrade':
        $className .= '\UpgradeData';
        $interface = self::DATA_UPGRADE;
        break;
