Looks like operator hb_array_t<> from vector works here. :)

* Update hb-ot-cff-common.hh

* fix bug

* bummer fix wasn't hit. refix

* additional sanity check

* Added test cases for oss-fuzz issues 11805, 11806

* add fd index checks to subr subsetter

also added oss-fuzz test case

* undid SubrSubsetParam::is_valid

because already validated by SubrClosures.valid

Will become default and option removed in the future.

This reverts commit 7146718b.
