[Decompilation] [th05] Mima's shot control functions And if I don't manage to cover Reimu in this push, it's because ZUN switched around the cases in half of the functions here… 😵 Here's some macros instead, to make the code at least *look* as table-driven and readable as it should have been in the first place. Part of P0037, funded by zorg.

[Maintenance] [th04/th05] Add a segment split before the title popup functions A bit tricky with those ASM translation units near-calling functions in the very first segment, and #pragma codeseg requiring an additional group parameter to correctly calculate array offsets (including those used for `switch` statements). But doable. Part of P0089, funded by [Anonymous] and Blue Bolt.

[Maintenance] [th05] Minimize #includes for the shot type translation units Since a few annoying alignment bytes suggested more translation units than previously expected, using many small headers has proved to be better than one big shared TH04/TH05 header file. Or should we *really* pepper the code with lots of `#pragma codestring`? 😛 And in case we have multiple translation units which all #include the same set of headers, we'll just go with situational shared headers, using a common prefix.

[Build] Don't word-align everything by default Again, 11 necessary workarounds, vs. forcing byte aligment in at least 18 places, and that number would have significantly grown in the future. Part of P0085, funded by -Tom-.
