sliptonic bb172e4a6b CAM: Renaming of postprocessors and cleanup (#24771)
* Post Processor cleanup and rename

remove unused files
Basic implementation of generic post
add blending mode support for linuxcnc
add mocking for postprocessor tests
Add tests for generic post
linuxcnc test only tests linuxcnc specific functionality

minor improvements
add arc splitting to refactored post processors
Refactor smoothie post
move posts to legacy.  Remove 'refactored'
lint cleanup
fixes #19417

* [pre-commit.ci] auto fixes from pre-commit.com hooks

String substitution allows the following:
%D ... directory of the active document
%d ... name of the active document (with extension)
%M ... user macro directory
%j ... name of the active Job object
The Following can be used if output is being split. If Output is not split
these will be ignored.
%S ... Sequence Number (default)
Either:
%T ... Tool Number
%t ... Tool Controller label
%W ... Work Coordinate System
%O ... Operation Label
|split on| use | Ignore |
|-----------|-------|--------|
|fixture | %W | %O %T %t |
|Operation| %O | %T %t %W |
|Tool| **Either %T or %t** | %O %W |
The confusing bit is that for split on tool, it will use EITHER the tool number or the tool label.
If you include both, the second one overrides the first.
And for split on operation, where including the tool should be possible, it ignores it altogether.
