Routine Description:
Start measurement according to token field. Inserts data into pre-allocatede memory buffer
Updates FPDT table using protocol API
Arguments:

Host - Host to measure
Timestamp - Ticker as start tick
Identifier - Identifier for a record
Returns:
EFI_SUCCESS - Located protocol successfully, and buffer is updated with new record
EFI_BUFFER_TOO_SMALL - Allocated memory is not enough to store new function
