Adds title screen section to tutorial

[Les-Wet]

Duplicate of 132 and 83. Had to create new PR due to forking issues on GitHub (cannot have more than one fork and forking wilersondevon's repo caused issues for other PR's).

I will start by implementing some of the feedback regarding the coding style, then move on to the tutorial text.

In the original PR #83, @CodeWithMa mentioned that this tutorial should use MemCopy since it will follow the Functions section. I have changed main.asm to take this into account. I have also included a build script to build the title-screen files with the new CI/CD that was just merged.

@AntonioND also mentioned that input.asm should follow the code style of the rest of the repository regarding indentation. Should this maybe be implemented in a separate PR? The input.asm is taken from the Input section of the tutorial and so there are two copies of the file to edit.

Another point regarding the input.asm file is that in the Input folder of the repository, the file is present but is not necessary for the build. This is because the relevant portion of this file is copied and pasted into main.asm. The build script I just added to the title-screen folder builds both the input.asm and the main.asm files. All other build scripts only use main, should this be changed to stay coherent with the rest of the code in the tutorial or should it simply be explained in the tutorial text?
