[TASK] Move t3lib/stddb files to ext:core

* Create one file per TCA table in ext:core/Configuration/TCA
* A single TCA file returns the full array definition of a table
* Merge TCA 'columns' and 'ctrl' definition in one file
* Move t3lib/stddb/tables.php to ext:core/ext_tables.php
* For now, let ext:core/ext_tables.php require TCA files
* The T3LIB: prefix of dynamicConfigFile definitions is obsolete
