+ Record operations that need to be replayed during an S3 resume.
+
+ This function is used to store an OpCode to be replayed as part of the S3 resume boot path. It is
+ assumed this protocol has platform specific mechanism to store the OpCode set and replay them
+ during the S3 resume.
+ The opcode is inserted before or after the specified position in the boot script table. If Position is
+ NULL then that position is after the last opcode in the table (BeforeOrAfter is TRUE) or before
+ the first opcode in the table (BeforeOrAfter is FALSE). The position which is pointed to by
+ Position upon return can be used for subsequent insertions.
+
+ 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.

+ NULL then the new opcode is inserted at the beginning of the table (if TRUE) or end
+ of the table (if FALSE).
+ @param[in, out] Position On entry, specifies the position in the boot script table where the opcode will be
+ inserted, either before or after, depending on BeforeOrAfter. On exit, specifies
