Drop support for the legacy session directory and optional store encryption.

Store encryption became mandatory in #2692
Rust's sessionPath replaced the legacy session directory in #2903
Native sliding sync migration resulted in new restoration tokens for new users in #3071 and later for all users by #3801.
