Test from https://github.com/behdad/harfbuzz/issues/223

Do not allow recursiving to same position and same lookup
...
This is just to make it harder to be extremely slow. There definitely
are ways still, just harder. Oh well... how do we tame this problem

Add tests for previous two commits
...
To fully test what these are supposed to test, they should be run
against libharfbuzz-fuzzing.la instead of libharfbuzz.la, but for
now just record the files.

[ot-font] Fix hmtx table length checking, *again*
...
Exactly the same problem that I fixed in
63ef0b41dc
I rewrote the table checking yesterday in
67f8821fb2
and introduced the exact same issue again. :(
Good thing we have ongoing fuzzing going now. Was discovered
immediately by libFuzzer. Thanks kcc!

[ot] Make bad-hmtx handling match FreeType
...
Also route fuzzing-related tests through hb-ot-font, to reduce dependency
on FreeType behavior for badly-broken fonts. Fixes failing test with
FreeType master.
