gatemate: use CPE bridge (#1538)
* Add bridge support

* Use bridge only if CPE is unused

* do not use CPE_MULT for MUX routing

* Fixed and documented

* delay for CPE_BRIDGE

* Convert bridge pips into bels

Co-authored-by: Miodrag Milanovic <mmicko@gmail.com>

* recursively reassign bridges

* reconnect cell ports to new nets

* handle inversion bits

* sort data in output for easier compare

* one to be removed after testing

* debug message

* Remove need for notifyPipChange

* use same logic for detecting bridge pips

* make sure that the pip used is the one assigned

* one wire may feed multiple ports

* remove #if

* clean up wire binding

* add debugging

* fix

* clangformat

* put back to error

* use tile instead of getting name out of bel/pip

* bump chipdb

* adressing review comments

* Addressed last one
