Move IDL copy logic into generate.py so we can individually update files

[andy31415]

Problem

IDL files for matter are only copied/moved when regenerate-all is run, which is slow.

Change overview

Move the logic into generate.py

Testing

Manually ran the generate (with changed zapt) and observed differences.
CI will validate that this is a "no changes" operation.

[andy31415]

Fast track: NOOP change generally, does not affect SDK functionality (treating it as testing code)
