[Maintenance] Clean up PI function declarations and comments

#include "th03/formats/pi.h"
[Maintenance] Drop the `slot` infix for PI-related identifiers ZUN doesn't ever use PI functions without these slots, making that infix kind of redundant. Part of P0114, funded by Lmocinemod.

int pascal pi_free(int slot);
[Reverse-engineering] [th05] Masked PI display As used for the title screen fade-in effect. Another function that apparently was deliberately written to run not that fast, by blitting each row individually to the 400th VRAM row just so that it can then turn on the EGC, perform the *actual* masked blit to the VRAM destination, and then turn the EGC off before moving to the next now. The same effect could have entirely been accomplished by copying graph_pack_put_8() and applying the mask there; it's not like ZUN didn't know how to modify master.lib… (See also 44ad3eb4) --Nmlgc

[Maintenance] Declare distinct types for screen, VRAM, and TRAM coordinates Whew, time to look at every `int` variable we ever declared! The best moment to do this would have been a year ago, but well, better late than never. No need to communicate that in comments anymore. These shouldn't be used for widths, heights, or sprite-space coordinates. Maybe we'll cover that another time, this commit is already large enough. Part of P0111, funded by [Anonymous] and Blue Bolt.
