Bindings generation spawns sub processes for each idl files, but fork/exec pattern is very slow on Windows. To reduce the process generation, control script can pass several files at once to the process.

Here is a statistics for 796 idl files:

Current imprementation: 386 secs
Batching 10 files:       63 secs
Aggressive approach:     36 secs (rest of files / number of process)
