/**
Adds a record into a specified Framework boot script table.
This function is used to store a boot script record into a given boot
script table. If the table specified by TableName is nonexistent in the
system, a new table will automatically be created and then the script record
will be added into the new table. A boot script table can add new script records
until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only
meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is
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.
@param This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance.
@param TableName Name of the script table. Currently, the only meaningful value is
EFI_ACPI_S3_RESUME_SCRIPT_TABLE.
@param OpCode The operation code (opcode) number.
@param ... Argument list that is specific to each opcode.
@retval EFI_SUCCESS The operation succeeded. A record was added into the
specified script table.
@retval EFI_INVALID_PARAMETER The parameter is illegal or the given boot script is not supported.
If the opcode is unknow or not supported because of the PCD
Feature Flags.
@retval EFI_OUT_OF_RESOURCES There is insufficient memory to store the boot script.
