Move some XFA JS code into fxjs/

This CL renames cxfa_scriptcontext to cfxjse_engine and
cxfa_fm2jscontext to cfxjse_formcalc_context.

From reading the code, the script context appears to handle the v8 setup
and object code. The formcalc context code is related to handling the JS
code generated from the transpiler.

I, think, these new names make the intended usage clearer. They also
move the code into fxjs/ to keep along side the rest of the JS code.
