smmstoretool is effectively a UEFI variable store writing tool, with a specific emphasis on the SMMSTORE backend implementation. However, it could also support other backends. Since it's typical for the variable store to be `n / 2 - 1` blocks, but not typical how large each block should be, allow this to be overridden on the command line. This is necessary because in EDK2, the module producing the firmware volume block protocol, the backend, will initialise a HOB or set PCDs to indicate the size of the store to the rest of the stack, and an assertion will be hit if the store has been preseeded by smmstoretool using differently-sized blocks. For example, `make CFLAGS=-DSMM_BLOCK_SIZE=8192` builds this for a firmware volume block protocol implementation with 8K blocks.
