In metadata:
	Fix #75172
	* icall.c (ves_icall_Type_GetMethodsByName): Don't use vtable_size
	for interface classes.  Use 'num_methods' instead.
	(ves_icall_Type_GetPropertiesByName): Likewise.  Setup vtable
	before using '->vtable_size' field.

In tests:
	* iface-large.cs: New test based on #75172.
