Transform BOOL and Win32 return values

[kennykerr]

Currently, the windows crate will transform API functions that return HRESULT or NTSTATUS into Result<T> to provide a more idiomatic developer experience.

This update extends that transformation to functions that return WIN32_ERROR, like RegOpenKeyExW, as well as functions that return BOOL and also have metadata that indicates they call SetLastError on failure, like LookupPrivilegeNameW.

Fixes: #2467

CC @talagrand and @riverar if you'd like to spot check.

Thank you @kennykerr! I spot checked all the APIs I was using and they're all covered by this PR.

Now, I can open a separate issue for this but it would be ideal if APIs that use the pattern sentinel + GetLastError() were also covered. Things like ExpandEnvironmentStringsW (returns 0 on failure) or ResumeThread (returns -1) or GlobalLock (returns NULL).

This will require additional metadata support; do file an issue at https://github.com/microsoft/win32metadata/issues thanks!
