Add option to disable Matcher errors (#6125)

Browse Source 
* Add option to disable Matcher errors

* Add option to disable Matcher errors when a doc doesn't contain a
particular type of annotation

Minor additional change:

* Update `AttributeRuler.load_from_morph_rules` to allow direct `MORPH`
values

* Rename suppress_errors to allow_missing

Co-authored-by: Matthew Honnibal <honnibal+gh@gmail.com>

* Refactor annotation checks in Matcher and PhraseMatcher
