[build] Fix of antlr#3269 (Remove all mentions of "Antlr4cs") (antlr#…

…3270)

* Remove Antlr4cs support and mentions.

* Remove _scripts, .github from consideration of testing as there are no desc.xml there. Code from ChatGPT4!

* Fix build crash when directory is removed on a git diff.

* Fix bcpl problem with newer trgen (grammar should only be bcpl.g4, not both g4's in the directory. Update ambiguous situations in grammars for testing.

* Remove debugging output.
