Mike Bayer 5cf8e14d58 Reflect "NO ACTION" as None; support "RESTRICT"

The "NO ACTION" keyword for foreign key "ON UPDATE" is now considered to be
the default cascade for a foreign key on all supporting backends (SQlite,
MySQL, PostgreSQL) and when detected is not included in the reflection
dictionary; this is already the behavior for PostgreSQL and MySQL for all
previous SQLAlchemy versions in any case.   The "RESTRICT" keyword is
positively stored when detected; PostgreSQL does report on this keyword,
and MySQL as of version 8.0 does as well.  On earlier MySQL versions, it is
not reported by the database.

Fixes: #4741
