Rename fxjse/ to fxjs/ update files to match class names.
This Cl moves the fxjse/ directory to fxjs/ in anticipation of merging in fpdfsdk/jsapi. In the process the filenames are updated to better match the class contents. Static methods are moved to anonymous namespaces as possible. Review-Url: https://codereview.chromium.org/2136213002
