Module schema management functions from schema.inc are deprecated

The following functions from schema.inc have been deprecated:

• drupal_install_schema()
• drupal_uninstall_schema()
• _drupal_schema_initialize()
• drupal_get_module_schema()

No direct replacement is provided, as these functions were only intended for use by the module installer service.

Tests that previously called drupal_get_module_schema() to inspect schema specifications can use a new static helper:

$schema = drupal_get_module_schema($module, $table);

becomes

use Drupal\TestTools\Extension\SchemaInspector;

$module_handler = $this->container->get('module_handler');
$specification = SchemaInspector::getTablesSpecification($module_handler, $module);
$schema = $specification[$table];
