Remove some abstractions in fxjs_v8.h.

It's too hard to keep mapping between v8 and fx abstractions; the lack
of transparency prevents those skilled in v8 only from working on this
code.

Apparently, the original intention was to confine v8 types to
fpdfsdk/{include,src}/jsapi, but fpdfsdk/{include,src}/javascript
is already well-polluted with v8 types.

Also remove no-op JS_SetThisObj().

Also remove unused ParserParams() [noticed because it was incorrectly
passing handles as pointers].

Also remove cast operator from CJS_Runtime and call GetIsolate()
explicitly.
