[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.

[Maintenance] Remove the old `planar(8|16|32)_t` types All code that used them has transitioned to C++, and can use the Planar<> template. Part of P0125, funded by [Anonymous].

[Maintenance] Declare a distinct type for VRAM offsets … and this one, while I'm at it. I've been using pretty much every possible type for VRAM offset variables, depending on my mood that day, since signedness apparently never matters for those. Except that it does. And so, just like with most of our high-level types, we also have to account for ZUN's little signedness inconsistencies here. Oh well, at least it's now only one of two types, and there's no need to choose between `int` or `unsigned int` or `short` or `unsigned short` or `int16_t` or `uint16_t` or `size_t` or… Part of P0111, funded by [Anonymous] and Blue Bolt.

[Maintenance] Declare distinct types for pixel and VRAM sizes Oh wait, we also need one of those for an upcoming structure! Part of P0111, funded by [Anonymous] and Blue Bolt.
