chore: remove native_mate (Part 3) (#20131)
* use gin converter in atom_api_menu

* please only put necessary includes in header

Having include in header means they have dependency relationship,
putting arbitrary includes really really really really really makes
refacoring much harder.

* remove some simple uses of callback_converter_deprecated.h

* use gin callback converter in file_dialog code

* use gin in ErrorThrower

* use gin in atom_bundle_mover

* fix mistake in node stream

* deprecate native_mate version of event_emitter_caller

* use gin in node_bindings

* remove usages of native_mate event_emitter_caller.h except for EventEmitter

* fix compilation on Windows

* gin::Arguments behaves differently on GetNext

* just use StringToV8
