Move source/matrix_free up in build order #15413

When compiling with a moderate number of threads, say between 10 and 30, the files taking a long time to compile inside the source/matrix_free can lead to a loss of parallelism when invoked towards the end of the build. These were initially added rather recently before the 9.3 release with dc4efca. This PR makes sure that the matrix_free folder is among the first targets, making sure the long-running tasks get started early enough. (This is for make; ninja likely does this on its own.)
