Deprecate the use of DECOMP_ME_WIP comments (#1339)

We have now fully decompiled every function which had a DECOMP_ME_WIP
comment, and we do not expect to ever have a need to add one in the
future.

Therefore, the function finder can be simplified by removing the process
of searching for these.

With no DECOMP_ME_WIP strings, `get_c_files` will never append anything
to `files`, so it always returns an empty list. We can therefore remove
the function.

With `c_files` always being an empty list, iterating over it will do
nothing, so we can remove `c_files` and the entire block of `for c_file
in c_files`.

Those are all the changes being made here, pretty simple.
