[android] Fix java runner to not assume zip format when unzipping

After dotnet#112256 landed, there was a change to zip the test assets
using `ZipFile.CreateFromDirectory` for cross platform support. This regressed `unzipAssets` in `MonoRunner.java`
because it naivley assumed that directories would come before files in the zip archive.

This change fixes the problem by making sure directories are created first before writing files to disk.

Fixes dotnet#112558
