clang/win: Fix a few warnings/errors.

Add throw() declarations to fix clang compile errors and match the declarations in the MS SDK.

This is a followup to https://codereview.chromium.org/447513002

Also, cfree is deprecated and certainly isn't available on Windows, so removing the code.

BUG=82385
