fix: rm new shared libs before build for Windows (#5541) 
On Windows, shared libraries must be removed before linking. Otherwise,
linking can fail with "Permission denied" when the libraries are in use.
This ensures such removal is done for the new `libLake_shared.dll` and
both parts of `libleanshared`.
