Fix #264, CodeQL Dependent on a Successful Build

Add two workflows for building and testing cFS in both RTEMS 4.11 and 5
Add scripts folder into .github for running all unit tests inside QEMU
Use dockerhub to store docker image containing all QEMU and RTEMS
toolchain and dependencies

Address PR comments by jphickey:
  Remove monitoring of stdout by correctly using batch-mode option
  Correctly use make SIMULATION variable instead of manually modifying
  targets.cmake during the actions workflow.

Address PR comments by zanzaben:
  Remove forgotten targets.cmake target system

Use makefile to run qemu tests and create qemu disk images instead of
shell scripts

Use wildcard matching to find and run all unit tests. Skip network tests
that fail with the SKIP_NET_TESTS flag.

Clean .mk scripts, ignore failing network tests

Run network tests to see github failure behavior

Remove  from output failed tests step
