fix RIDER-130140 GDScript: parsing fixes

[van800]

I am investigating an issue with the following codes.
It seems that parser remaps DEDENT-s inside func(): too agressively thus in GdStmtParser#suite we exit on the second line if (!b.nextTokenIs(NEW_LINE)).

func asd():
	print(
		func():
			if 0 > 0:
				pass
			elif 0 < 0:
				pass
	)

and

	lifetime.timeout.connect(func():
		if is_instance_valid(projectile):
			projectile.queue_free()
			print("Projectile freed")
	)

This seems to fix broken lambda parsing in my project! Haven't checked every single lambda yet (still lots of red in my project) but it's a big improvement.

I did find another lambda parsing issue, filed RIDER-131046

likely need to change gd.frlex
in a way that inside lambdas and brakets, curly brakets indentation is ignored until we are in a statement like "if"

	d = {22:

        "value"

	,

   "some_key"

		: 		func():
			if 0 > 0:
				pass
				pass
			elif 0 < 0:
				pass
				pass
				,
		"other_key": [2, 3, 4],
		"more_key": "Hello"
	}
