Supersize: Add sources for large .other symbols

These large binary files are copied over to the root output directory
and then copied into the apk. There is no good way to propagate their
source paths like pak or dex since they are plainly copied.

These files rarely, if ever, change. Some are even renamed from the
actual source file to this final name. Thus adding them as constants.

res/* and the rest of .other symbols are relatively small. Leaving those under *.apk.

Let's re-open for res/. There is potential for much more res/ to be added, and currently it's actually not that small (~1.3mb). Adding source paths should be fairly straight-foward to do in the same way we did pak (each prepare_resources.py invocation can write a .info file).

I agree it's not high priority though.

Sounds good, updated summary to reflect what we want to do.

I would like to actually do this earlier since we want to stable mappings earlier to compare between milestones.

Supersize: Properly attribute res/ symbols

Create .info files for resources during jinja processing, aapt2
compressing, and aapt2 linking, using these .info files to create a
per-apk *.apk.res.info file that supersize then uses to properly map a
resource file back to its source file.

There is some complexity with resource overloading and android build
tools changing the resource file or directory as part of packaging an
apk. This is handled by a combination of storing renames and parsing
heuristics.
