CFF renaming (#1507)
* reimplement ByteStr as byte_str_t based on hb_ubytes_t
Unuse start_embed<ByteStr>
Also renamed SubByteStr to byte_str_ref_t
More renaming to come
* substr renamed to str_ref in line with its type byte_str_ref_t
* uncamelize non-table struct names
* uncamelized non-struct types OpCode etc
* add byte_str_t copy ctor
* test
* test2
* undo tests
* fix bot failure
* undo the previous change
* fixed tabs, added inline
* Revert "fixed tabs, added inline"
This reverts commit 21163c30e9d18759414f7fe2518628241599f039.
