There should be an up-front check of the alignment when constructing a VarHandle via the MemoryLayout::arrayElementVarHandle method.

When we create a strided var handle, we should check that the layout has a size multiple of its alignment (as the layout is going to be used as an element layout).

Reproduce:

jshell> import java.lang.foreign.*;

jshell> import java.lang.invoke.*;

jshell> var HYPER_INT = ValueLayout.JAVA_INT.withByteAlignment(8);
HYPER_INT ==> 8%i4

jshell> var HYPER_HANDLE = HYPER_INT.arrayElementVarHandle();
HYPER_HANDLE ==> VarHandle[varType=int, coord=[interface java.lang ... emorySegment, long, long]]

jshell> var segment = Arena.ofAuto().allocate(100);
segment ==> MemorySegment{ address: 0x7ff500273040, byteSize: 100 }

jshell> HYPER_HANDLE.get(segment, 0, 0);
$6 ==> 0

jshell> HYPER_HANDLE.get(segment, 0, 1);
| Exception java.lang.IllegalArgumentException: Target offset 4 is incompatible with alignment constraint 8 (of 8%i4) for segment MemorySegment{ address: 0x7ff500273040, byteSize: 100 }
