Create the new method Drupal\Core\Database\Connection::getPrefix() and deprecate Drupal\Core\Database\Connection::prefixTable($table)

Problem/Motivation

We now have the method Drupal\Core\Database\Connection::prefixTable($table) which returns the prefix for the table. In D9 and before there was the possibility to have different prefixes for different tables. In D10 there is only a single prefix for all tables. The method and its parameter suggest that it is still possible to have per table prefixing. This does not improve the developer experience.

Proposed resolution

Deprecate method Drupal\Core\Database\Connection::prefixTable($table) and create the new method method Drupal\Core\Database\Connection::getPrefix(). The new method has no parameters. It just return the class variable $prefix.
