feat: record [grind homo] source types - #14457

Conversation
This PR records the homomorphism source types of a `[grind homo]` theorem set: when an `=`-injection rule (a rule translating `Eq τ`) is registered, the head constant of `τ` is added to a new environment extension, and rules whose source type is not headed by a constant are rejected. The source types identify the terms the `grind` homomorphism engine must track in the E-graph. The `reset_grind_attrs%` command clears the new extension.
