fix(orm): add additional checks on invalid tables (#11387)

## Description

Adds checks for two types of errors in table definitions
* defining a key on an `optional` field (haven't found a way to test unfortunately because a test case will break the code generator)
* defining a trivial unique key, essentially a unique key which contains all the fields in the primary key and is redundant
