chore: Fix files for PC Engine / PC Engine CD

[leocck]

What does this PR do?

This PR organises the CHT files from PC Engine and PC Engine CD 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:

• The cht files were all renamed to match what the DAT/RDB files defined, so that they could be found (Rumbles included). Many of them were just cosmetic changes (special characters, ordering, suffixes), and some other were a bit more tricky and required more investigation (versions, regions, etc.)
• Some CD files were in the wrong folder and were moved around
• There were duplicated cheats spread in two different cht files for the same game, they were merged into a single one, keeping the "1F0000:00" format as standard for these two systems

I used a preservation strategy and kept all information when there was no way to be sure which region/version the cht file was pointing to:

• In cases where there were two options (region or revision), I decided to duplicate the cht file and leave one for each of them, so that the validation could be done later
• When merging cht files for the same game, I preferred to remove only the exact duplicates, and kept the other codes as "Alternatives"
• When a cht was specifying some extra region that was not included in the RDB, I kept it (did not delete it)

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• I also checked the cht files that did not have a match in the DAT/RDB, most of them turned out to be unpublished/alternative games
