Add reverse debugging (#1918)

Browse Source 
* Add initial reverse debugging support

* Add reverse debug icons

* Added an option to stop the debug session and enabled continue and step back

* Added a new icon for stop trace and recolored start trace

* Toggle reverse debug actions when not tracing

* Stop existing trace sessions in stopDebug

* Ported to Rizin

* Set reverse icons to invisible when not in a trace session instead of disabled

* Updated rizin submodule

* Cleaned up step and continue events

* Apply clang format
