[subset-cff] Really optimize op_str_t / parsed_cs_op_t layout
...
Now parsed_cs_op_t and op_str_t are both 16 bytes.
Saves another 7% in SourceHanSans/10000 benchmark.

[subset-cff] Readjust parsed_cs_op_t
...
Now it doesn't matter anymore since op_str_t is adjusted and
is 16 bytes with 8byte alignment.

Make it 16 bytes instead of 24. This struct is used in the subroutine
call stack heavily.
This change makes the HB AdobeVFPrototype benchmark to become faster
than FT one, with about 6% speedup as a result of this change.
