[Maintenance] Rename all old *_X and *_Y constants to *_LEFT and *_TOP Part of P0112, funded by [Anonymous] and Blue Bolt.

#define PLAYFIELD_LEFT (32)

[Position independence] False positives in master.lib GRCG function calls Yup, function parameters that can clearly be identified as coordinates are by far the fastest way to raise the calculated position independence percentage. Kinda makes it sound like useless work, which I'm only doing because it's dictated by some counting algorithm on a website, but decompilation will want to un-hex all of these values anyway. We're merely doing that right now, across all games. Part of P0058, funded by -Tom-.

#define PLAYFIELD_VRAM_LEFT (PLAYFIELD_LEFT / BYTE_DOTS)
[Maintenance] #define the number of dots in a byte One fewer magic number. And one more deliberate dependency on a PC-98-specific hardware constant, to further drive home just how unportable these games are, even once decompilation will be complete. Part of P0105, funded by Yanga.
