feat: support configurable constant-fold exclusions

[fs-eire]

Description

This PR introduces a new lowering pass mark_constant_fold_exclusions just before the constant_fold pass. The new pass is used to mark specific nodes so that they will not be constant folded in the next pass.

The feature uses a rule based, configurable approach. There are pre-defined rules, and by default all rules are applied. User can use a disabled_constant_fold_exclusions setting to disable one or more rules by specifying the rule name.

Currently, this PR should not affect the behavior because the rule list is empty. I will work on add a new rule related to attention in the next PR, which depends on the current PR.
