[llvm-rc] Add missing inputs for tag-icon-cursor.test.

[mstorsjo]

Summary

This adds the missing input files used for this test, except for the separate input files for specific error cases; matching test input files were provided by Nico Weber. (I found test input files at https://github.com/nico/hack/tree/master/res/test that seem to match most of the missing ones for the existing icon/cursor test.)

The extra copying of files into the %t directory doesn't seem to be necessary since that directory only ever is used for output here, not for inputs.

FWIW, the previous value here seems to be what rc.exe produces, so something is wrong in the current codebase. But improving the test coverage for the current code as it stands probably also is worthwhile, even if there are known issues?

From the Wikipedia info on the ICO format, this appears to be the bits-per-pixel field (assuming it's an icon and not a cursor). There's a note that says the field may be 0 (in most cases) because the bits-per-pixel can (usually) be inferred.

My guess is the source file has 0 and llvm-rc copies it verbatim while rc.exe infers the BPP and sets it explicitly. In theory, it should work either way.

Maybe add a comment here so that if we ever do match rc.exe, nobody has to sweat the details to make the test pass.

Ah, I see you figured out the discrepancy in a follow-on patch (46816), so this LGTM.
