chore: Fix files for MSX

[leocck]

What does this PR do?

This PR organises the CHT files from MSX and MSX2 systems.

Disclaimer: I did a lot of manual evaluation and work. I did not rely on AI besides creating some controlled automation scripts

Context

The cht files from these two systems had many issues that prevent OpenEmu-Silicon emulator and any other emulator to find them.

The fixes required a lot of manual work and validation with game roms. As part of the work, the most important things were:

• Figuring out which game the cht files were connected, and from which system
• Renaming the cht files to match what the DAT/RDB files defined, when existing, or to the plain game name
• Some games have multiple names (e.g., English / Japanese / Spanish), and the closest name from the cht file was kept
• Cheat codes from both fMSX and blueMSX were merged into a single file, removing duplicates and marking blueMSX as "Alternative" codes

What was Tested

• First, I tested a couple of games manually to see if cheats were working on the emulator.
• After renaming the files, I tested if the emulator would match them based on the DAT/RDB entries
• I also checked the cht files that did not have a match in the DAT/RDB, as a fallback OpenEmu-Silicon would find them by the plain name
