CAM: Added test of Fanuc post processor
Used TestMach3Mach4LegacyPost.py as the starting point with input from other test scripts too. The test demonstrate a fix for #25723, as the Fanuc post processor has not been not updated to the latest changes in the Path module. This is related to #24676, where thread tapping was added to LinuxCNC, but the equivalent code in the Fanuc postprocessor were not adjusted to cope, and #25677 where it was observed that the Fanuc postprocessor was broken in versions 0.20 and 1.0. Added MockTool class to provide ShapeName to fanuc_post.py, used to convert drill cycles to threading cycles if the tool has shapeid "tap".
