tests/tcg/tricore: Add macros to create tests and first test 'abs'
This kind of tests is inspired by the riscv-tests repository. This adds macros that makes it easy to create single instruction self containing tests. It is achieved by macros that create a test sequence for an instruction and check for a supplied correct value. If the value is correct the next instruction is tested. Otherwise we jump to fail handler that writes is test number as a status code back to qemu that then exits on that status code. If all tests pass we write back 0 as a status code and exit.
