Add option to display stack trace for errors and warnings

[pouleyKetchoupp]

Support for optional stack traces in log on errors and warnings, based on a project setting option to set the call stack size, from godotengine/godot-proposals#963.

Windows, Linux:
Implemented stack trace code in specific OS utility, used in common with the crash handler.

Note: On Windows, stack traces work only with MSVC, not with MingW (see #42540).

Other platforms:
Not supported yet.

Example script:

extends Node

func _ready():
	_test_error()

func _test_error():
	push_error("Test error")
	get_node("abc")

Example output:

ERROR: Test error

This is interesting, and I guess as long as not too confusing to users it would work also great for telemetry and other stuff if also other platforms are supported.

I've tried to rebase this PR, but it doesn't appear to work on Linux: https://github.com/Calinou/godot/tree/error-handler-windows
