+ will be added into the new table. A boot script table can add new script records

+ responsible for allocating necessary memory for the script.
+
+ This function has a variable parameter list. The exact parameter list depends on
+ the OpCode that is passed into the function. If an unsupported OpCode or illegal
+ parameter list is passed in, this function returns EFI_INVALID_PARAMETER.
+ If there are not enough resources available for storing more scripts, this function returns
+ EFI_OUT_OF_RESOURCES.
