[subset] don't visit lookup if covered glyph set has failed.
...
If covered glyph set is in error then the same lookup can be recursed into repeatedly potentially causing a fuzzer timeout. Fixes: https://oss-fuzz.com/testcase-detail/5416421032067072 .

[subset] Anchor should only use format 1 when hints are dropped.
...
Refactor Anchor to have a subset method instead of copy. This also allows
use to use serialize_subset in several places which simplifies calculating
offset bases.

[sanitize] change max ops to track number of bytes processed.
...
Counting bytes as the operations is likely to be a better proxy for how
much work processing the table will cost vs. the current approach of
counting the number of sub-objects.
This should allow checks for max features, max scripts, etc. to be removed.
I tested this change against the full collection of fonts at https://github.com/google/fonts
and a max ops factor of 3 was sufficient to successfully sanitize all of them.

hb-config: Include config-override earlier
...
Currently config-override.h is included at the end of this file. This caused a problem for me while undefing HB_DISABLE_DEPRECATED, namely HB_IF_NOT_DEPRECATED was defined before actual undef took place and broke the whole build. I believe it would break builds for some other defines, too. Moving config-override.h include right after predefined configs is more sane and fixes all potential problems with includes.
