[bundle] Include cross*.d* in the bundle

Commit a08cd80 updated `mono-runtimes.targets` to copy e.g.
`cross-arm64.exe` to `cross-arm64.d.exe`, then to *strip*
`cross-arm64.exe` in an effort to (eventually) reduce `.vsix` size.

While admirable, there was one oversight: the original un-`strip`ped
`cross-arm64.d.exe` *wasn't* added to the bundle, meaning the copy
with debug symbols is *lost*.

Oops.

Correct this oversight and add `cross-*.d*` to the bundle.
