timestamp,amd/common/apob_cache: Add timestamps for APOB

Updating the APOB takes a considerable amount of time. I decided to be
granular and split out the operations so we know when we read vs read +
erase + write.

BUG=b:179092979
TEST=Boot guybrush and dump timestamps
   3:after RAM initialization                          3,025,425 (44)
 920:starting APOB read                                3,025,430 (5)
 921:starting APOB erase                               3,025,478 (48)
 922:starting APOB write                               3,027,727 (2,249)
 923:finished APOB                                     3,210,965 (183,238)
   4:end of romstage                                   3,210,971 (6)
