[FEATURE] Auto DB fields from TCA for type "file"

Tables with TCA columns set to type="file" do not
need an ext_tables.sql entry anymore. The core now
creates this field automatically.

This is the first patch in this area: The v13 goal
is to obsolete ext_tables.sql in most cases by
creating default "business" fields of TCA tables
automatically.

The patch adds the main magic in class DefaultTcaSchema
and removes own ext_tables.sql definitions having
type=file.
It goes through various functional test related .csv
fields, and adapts a broken TCA configuration in the
blog_example fixture extension revealed by this change.
