This gets rid of a couple of per-entity sprite bitplane types, makes
sprite declarations easier to read by putting width and height next to
each other… and points out a number of array dimension mistakes -.-
Even in places where we can't use it.

Might look uglier, but has the advantage of not generating an empty
segment with the default name… *and* the default padding, which will
really come in handy with the following breakthrough.

eeb4e7e changed the final C translation unit that used this header to
C++, and we got some more helpful inline functions upcoming.

If anything, these decompilations of barely decompilable functions can
at least indicate that I tried. 🤷 Nice __fastcall abuse though, which
allows us to least formalize *some* of the implicit state passed
between those functions.

Reasons:
• piano_fm_part_put_raw(): SI register referenced and not saved on
the stack
• piano_current_note_from(): Would be decompilable… into a mess.
Not worth adding a separate translation unit just for it.
• piano_part_keys_put_raw(): DI register saved before the SI register
• piano_pressed_key_put(): DI register referenced and not immediately
saved on the stack
• piano_label_put_raw(): SI and DI registered referenced and not saved
on the stack
• grcg_setcolor_direct_seg1_raw(): Let's procrastinate this one until
we have to reference all of these instances in C land.
And we could have even emitted that PIANO_KEY_PRESSED_TOP pixel data
into the code segment, by using `#pragma option -z` to give identical
names to both the code and the data segment. At least we can decompile
the first two functions here.
