Fix component object property binding unwanted init reflow

[pushkine]

This is part of Svelte's issue with flagging objects and its overreliance on equality checks
Object bindings however can in part sidestep the issue in cases where a property is specified, as those often happen to be primitives, they may be checked instead
Fixes #3075, Fixes #4447, Fixes #5555

<Component bind:value={obj.property} />

function component0_value_binding(value) {
+	if ($$self.$$.not_equal(obj.property, value)) {
		obj.property = value;
		$$invalidate(1, obj);
+	}
}
