Add clear-caches console command

[khalwat]

This adds a clear-caches console command that mirrors the functionality provided in the GUI Clear Caches utility.

It works with all of the built-in Craft caches, as well as any third party caches that are registered:

- clear-caches                                          Clear caches via the CLI
    clear-caches/all                                    Clear all caches
    clear-caches/asset                                  Asset caches
    clear-caches/asset-indexing-data                    Asset indexing data
    clear-caches/compiled-templates                     Removes all of a directory’s contents recursively.
    clear-caches/cp-resources                           Control Panel resources
    clear-caches/data                                   Deletes all values from cache.
    clear-caches/fastcgi-cache-bust                     FastCGI Cache
    clear-caches/retour-redirect-caches                 Invalidate all of the redirects caches
    clear-caches/route-map                              Route Map Cache
    clear-caches/seomatic-frontendtemplate-caches       Invalidate all of the frontend template caches
    clear-caches/seomatic-metabundle-caches             Invalidate all of the meta container caches
    clear-caches/seomatic-sitemap-caches                Invalidate all of the sitemap caches
    clear-caches/temp-files                             Removes all of a directory’s contents recursively.
    clear-caches/template-caches                        Deletes all the template caches.
    clear-caches/transform-indexes                      Asset transform index

There are some merge conflicts in src/db/pgsql/Schema.php.

Also DynamicAction should probably be renamed to ClearCacheAction.

I synced the file src/db/pgsql/Schema.php to the upstream version

Also renamed DynamicAction to ClearCacheAction.
