FUNCTION: GetVarStoreInfo()
DESCRIPTION: IFR contains VARSTORE opcodes to specify where variable data
for following opcodes is supposed to be stored. One VARSTORE statement
allows you to specify the variable store GUID and a key, and another
VARSTORE (select) allows you to specify the key of a VARSTORE statement.
Given the key from a VARSTORE_SELECT statement, go find the corresponding
VARSTORE statement with a matching key and return the varstore GUID and
name. If key == 0, then the variable store is FormsetGuid."Setup"
