Made CPR optional, html generated at build time (#840)

- Fix potential crash on startup caused by logging macros being invoked before the logging system is initialized (null logger dereference in `ZenServerState::Sweep()`). `LoggerRef::ShouldLog` now guards against a null logger pointer.
- Make CPR an optional dependency (`--zencpr` build option, enabled by default) so builds can proceed without it
- Make zenvfs Windows-only (platform-specific target)
- Generate the frontend zip at build time from source HTML files instead of checking in a binary blob which would accumulate with every single update
