cpukit/libfs: Write the Doxygen briefs

The briefs of the file system files named a topic, not the content of
the file.  A reader could not tell which function a file defines.  The
blocks also placed @ingroup and @brief in several orders.

Write every brief in the style of the tree.  A source brief starts with
"This source file contains".  Where a file defines up to three
functions, the brief names them.  Where it defines a table or a whole
subsystem, the brief names that.  A header brief starts with "This
header file provides".

Put @file, @ingroup and @brief in this order in every block.  Any
further paragraph of a block stays as it is.

Updates #5717.
