[mdoc] Add mdoc and dependencies to the bundle

Context: 5a8e48eba8

`mdoc.exe` is used by the `<MDoc/>` task, used by the
`BuildDocumentation` target in `Xamarin.Android.Bindings.targets`.

We obtain `mdoc.exe` from the `external/mono` build, but because
`mdoc.exe` will be referencing mono's `Mono.Cecil.dll`, we use
`remap-assembly-ref` to update `mdoc.exe` to instead use
`Xamarin.Android.Cecil.dll`.
