Add /*<type>*/ comments everywhere (#2986) 
Adds /*<type>*/ comments and a linter check from rz-bindgen to enforce
their existence and consistency

Also includes the following fixes made when adding the annotations:
* removed unused intern_table arguments in pyc_dis.c, pyc_dis.h, asm_pyc.c
* removed unused classes argument from place_nodes in agraph.c
* removed unused recurse and recurse_bb functions in canalysis.c
* removed unused vars field from RzPrint struct
* removed unused RzAnalysisType* structs from rz_analysis.h
* removed unused list field from RzEgg struct
* fixed bug in bp_plugin.c where duplication-checking logic iterates over the wrong list
* removed unused q_regs field from RzDebug struct
* removed unused backtrace field from RzDebugPlugin struct
* removed unused classes_list field from RzBinNXOObj struct
* removed unused methods_list and classes_list fields from RzBinZimgObj struct
