Interpreter: Fix Store() when implicit conversion is not possible

Browse Source 
For the cases such as a store of a string to an existing package
object, implement the store as a CopyObject(). This is a small
departure from the ACPI specification which states that the
control method should be aborted in this case. However, ASLTS
suite depends on this behavior.
