Remove xfa/src/fxfa/src/common and xfa/src/fxfa/src
This Cl moves the code in xfa/src/fxfa/src/common to the diretory which contains the respective implementations and removes the xfa/src/fxfa/src/common directory. It them moves all of the code in xfa/src/fxfa/src up one level and removes the xfa/src/fxfa/src directory. R=tsepez@chromium.org Review URL: https://codereview.chromium.org/1770073003 .
