On the list of functions yet to be decompiled, these were at number 7
and 1, respectively, which corresponds to number 7 and 22 on the total
list of functions in PC-98 Touhou.

For once, I'm glad that ZUN copy-pasted this one-off function.
Otherwise, it probably wouldn't have been that easy to factor out.

In most cases, this discovery will mean that we have to bite the bullet
and remove `const` from pointer parameters if the generated ASM
wouldn't match otherwise. That by itself doesn't really simplify the
code, but at least we get to remove a single bloated `reinterpret_cast`
from one function call already.

Matching TH04 and TH05 functions, which differentiate between raw
sensing and resetting+sensing. In that light, the previous name for
TH02's function was rather misleading for leaving out that crucial
detail…

Needed for a constness overloading hack later. A certain single place
in TH02 will need the `str` parameter to not be `const` for code
generation reasons, but we don't want to force every call site into
passing non-`const` pointers for such a silly reason.

Also dropping the `_8` as it's irrelevant to a fullscreen image.
And yes, we'll see a version without palette mutation.

Another issue related to `public` that causes TASM32 version 5.0 to
crash. Better staying on that version from now on…
Thanks to spaztron64 for reporting this one!
Almost three years after the big SHARED segment separation got
unfortunately stuck thanks to this function, it's finally done!

So anticlimactic, again…
Also, note how renaming the `end_sequence_t` constants to better match
their usage also simplifies the explanatory comment for TH04's
not-quirk.

With the implementation moved to the header, it makes sense to
duplicate the function in the unfortunate place where the filename is
supposed to be.

Might as well give a more descriptive name to the variable than
something involving the generic `screen` (which we've started using for
coordinates) and the inconsistent `back` (which always means "back page
of VRAM", which has nothing to do with this bitplane).
Also, turns out that this was in fact the only place that did a 32-wide
memcpy() of a full VRAM bitplane.

Featuring a return of the recently developed `$ -` tech, along with
some unfortunate PI breaks… But hey, at least it makes sense to start
out with this move!
