twister: replace dt_compat_enabled_with_alias filter

Originally added in 7733b94.

This filter is not well-formed. It's meant to match nodes like
/leds/led_0 in this DTS:

/ {
	aliases {
		led0 = &led0;
	};

	leds {
		compatible = "gpio-leds";
		led0: led_0 {
			gpios = <...>;
			label = "LED 0";
		};
	};
};

Uses look like this:

    filter: dt_compat_enabled_with_alias("gpio-leds", "led0")

But notice how the led_0 node doesn't have compatible "gpio-leds";
it's actually the *parent* node that has that compatible.

Replace this with a new filter, dt_enabled_alias_with_parent_compat(),
which is used like this:

    filter: dt_enabled_alias_with_parent_compat("led0", "gpio-leds")

This has a name and argument order that makes the meaning of the
filter clearer.

Replace in-tree users with the new filter.

Deprecate the old filter and warn about its use using the standard
logging module.
