Cleanup the xfa/src/fdp directory.

This CL renames xfa/src/fdp to xfa/src/fde to better match all of the content
(nothing mentions fdp other then the directory name). The inner src/ and
include/ folders are collapsed up a level and xfa/src/fdp/src/fde is moved
up to xfa/src/fde.

Some of the header moves conflicted with existing headers. In that case, the
existing header had the content moved into the .cpp file and we replaced the
existing header with the one from include/.
