runtime(tutor): Make all tutor files utf-8 only
In this commit, all legacy encodings for tutor files are removed.
* All the tutor files `tutor1.xx` and `tutor2.xx` are now `utf-8`
* All `README.xx.txt` files are now `utf-8`
* All makefiles are removed, as they are no longer needed
* The `tutor.vim` script is simplified
* The `README` indicates `utf-8` as a requirement
* update vimtutor.bat file
In 2025, there is no realistic scenario where a beginner starts the Vim
9.1 tutor on a machine that lacks UTF-8 support.
This change will ease the maintenance of the tutor files. Cf #17562 for
an example.

Translation
-----------
-The files tutor1.xx and tutor1.xx.utf-8 for chapter one and tutor2.xx and
-tutor2.xx.utf-8 for chapter two of the tutorial are translated files (where xx
-is the language code).
-The encoding of tutor1.xx or tutor2.xx might be latin1 or other traditional
-encoding. If you don't need a translation with such traditional encoding,
-you just need to prepare the tutor1.xx.utf-8 or tutor2.xx.utf-8 file.
-If you need another encoding, you can also prepare a file named tutor1.xx.enc or
-tutor2.xx.enc (replace enc with the actual encoding name). You might also need
-to adjust the tutor.vim file.
-The "make" command can be used for creating tutor1.xx or tutor2.xx from
-tutor.xx.utf-8 or tutor2.xx.utf-8, respectively.
-See the Makefile for detail. (For some languages, tutor1.xx.utf-8 is created
-from tutor1.xx for historical reasons.)
+The files tutor1.xx for chapter one and tutor2.xx chapter two of the tutorial
+are translated files (where xx is the language code).
+The encoding of tutor1.xx and tutor2.xx must be utf-8.
