tests/tcg: clean up output of memory system test

This is useful information when debugging memory issues so lets
improve by:

  - include the ptr address for u8 fills (like the others)
  - indicate the number of operations for reads and writes
  - explicitly note when we are flushing
  - move the fill printf to after the reset
