Add ability to remove multiple elements from an array by index

[uberfig]

As far as I have been able to find, Godot does not have an method to remove multiple elements from an array by index, and I wasn't able to find any similar discussions

I think it could be quite beneficial to be able to have a built in method to remove multiple elements from an array. This method could take a dynamic amount of indexes or an array as input and remove the elements that were at those positions from the array
the function could look like:
array.remove_multiple(int ...)
adding this to the engine could make the following logic a bit cleaner and more performant

var foo:= []
func update_foo():
	var to_be_removed:= []
	for bar in foo:
		if bar == condition:
			to_be_removed.append(bar)
	for item in to_be_removed:
		do_stuff(item)
		var i = to_be_removed.find(done)
		to_be_removed.remove(i)

here is an example of what this logic could look like with the proposed changes:

var foo:= []
func update_foo():
	var to_be_removed:= []
	var count := 0
	for bar in foo:
		if bar == condition:
			to_be_removed.append(count)
		count+=1
	for item in to_be_removed:
		do_stuff(foo[item])
	foo.remove_multiple(to_be_removed)
