Remove limitations on validation types for eauth targets

When validate_tgt() was written, we did not have a CkMinions class nor
did we have a method of pre-matching minions. Therefore, only certain
match types were permitted.

This commit removes that limitation, allowing eauth targets to be
pillar, ipcidr, etc.

Fixes #30761.
