Move some common matrix code to a common location (#7699)

Browse source 
* Move some common matrix code to a common location

* Refactor some 'custom_matrix_helper' logic to use custom matrix lite

* Fix build for kinesis/stapelberg - abuse of vpath was picking up matrix.c from core when custom matrix was enabled

* Add validation for CUSTOM_MATRIX
