Use enum class instead of int in CJBig2_Contextchromium/3426

This CL changes CJBig2_Context return methods as follows:
* Internal methods return JBig2_Result instead of int.
* Public methods return a bool (for success/failure) instead of int.

In a followup, several of the enum class values may be merged together
since they are not all needed.
