Extend std::span adoption to utility and AST functions (#8271)

Browse source 
* Initial plan

* Add std::span to utility functions (buffer, ref_buffer, permutation, util)

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add std::span to ast_manager array ref functions

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Fix: Use consistent int loop variable in apply_permutation
