[memprof] Omit the key length for the record table (#89527)
The record table has a constant key length, so we don't need to
serialize or deserialize it for every key-data pair. Omitting the key
length saves 0.06% of the indexed MemProf file size.
Note that it's OK to change the format because Version2 is still under
development.
