Copilot d7481e71ba Fix max_decode_depth to control decoder hierarchy and port generation (#18)
* Initial plan

* Fix max_decode_depth to properly control decoder hierarchy and port generation

Co-authored-by: arnavsacheti <36746504+arnavsacheti@users.noreply.github.com>

* Fix test that relied on old depth behavior

Co-authored-by: arnavsacheti <36746504+arnavsacheti@users.noreply.github.com>

* Update documentation for max_decode_depth parameter

Co-authored-by: arnavsacheti <36746504+arnavsacheti@users.noreply.github.com>

* fix format

* Add variable_depth RDL file and smoke tests for max_decode_depth parameter

Co-authored-by: arnavsacheti <36746504+arnavsacheti@users.noreply.github.com>

* Add variable depth tests for APB3 and AXI4-Lite CPUIFs
