ArmPlatformPkg/BootMonFs: Fix the setting of information about a file
Rework the setting of information about a file, in particular
file resizing, file renaming and the returned error codes in case
of error. This rework has implied a rework of the read, write, close
and flush functions.
To strickly separate what has been actually written to the media (flushed)
from what has not been written when a file is open, an "Info" field has
been added to the description of a file.
The field is used to store the modifications done to the file by the
means of SetInfo() like the change of the name or of the size. Such
changes are written to the media only when a flush occurs.
When a file is open, the information pointed to by the "Info" field is
always up-to-date. This is not the case of the information stored in
the "HwDescription" of the file description which from now is just a
mirror of what is written on the media.
