Lua improvements

[glebm]

Multiple Lua improvements:

1. Follows advice from https://sol2.readthedocs.io/en/latest/functions.html to use set_function when binding functions.

2. Adds autocomplete support for userdata methods, including handling . vs ::

   

3. Updates Lua and sol2 (with some patches for yet-to-be-merged PRs).

@tsunamistate make sure you have patch.exe installed in your system PATH so that cmake can find it.

[tsunamistate]

@AJenbo my patch.exe was successfully found by FindPatch.cmake from the Git installation, if you read the log, you can see that some of the files were patched correctly, and it failed due to:
Hunk #1 FAILED at 23 (different line endings).

Oh, sorry about that. Can you try in the following order:

1. Pass the input to patch via -i inputfile instead of < inputfile.
2. Add --binary flag to the patch command.
3. Change the line endings of the patch file.

If none of that works, I suppose we could fork a diasurgical/sol2 repo and have a branch with the patches that we want.
