[pzstd] Fixes for Windows build

Browse Source 
* Add `Portability.h` to fix min/max issues.
* Fix conversion warnings
* Assert that windowLog <= 23, which is currently always the case.
  This could be loosened, but we aren't looking to add new functionality.

Fixes on top of PR #3375 by @eli-schwartz, which added Windows CI for contrib & programs.
