all: Rename *umodule*.c to remove the "u" prefix.
Updates any includes, and references from Makefiles/CMake. This essentially reverts what was done long ago in commit 136b5cbd7669e8318f8455fc2706da97a5b7994c This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
