GDScript call stack as reverse linked list with fixed coroutines

Browse source 
* GDScript call stack as reverse linked list with issues fixed
(originally proposed in 91006).
* Fix coroutine issues with call stack by resuming async call chain
inside `GDScriptFunction::call()`.
* This fixes corrupted line numbers for coroutines in the debugger and
backtrace (106489).
