This is an function to close the S3 boot script table. The function could only

EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable(), this function will fulfill following things:
1. Closes the specified boot script table
2. It allocates a new memory pool to duplicate all the boot scripts in the specified table.
Once this function is called, the table maintained by the library will be destroyed
after it is copied into the allocated pool.
3. Any attempts to add a script record after calling this function will cause a
new table to be created by the library.
4. The base address of the allocated pool will be returned in Address. Note that
after using the boot script table, the CALLER is responsible for freeing the
pool that is allocated by this function.
In Spec PI1.1, this EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is retired. This
API is supplied here to meet the requirements of the Framework Spec.
If anyone does call CloseTable() on a real platform, then the caller is responsible
for figuring out how to get the script to run on an S3 resume because the boot script
maintained by the lib will be destroyed.
@return the base address of the new copy of the boot script table.
