Define NOMINMAX in z_pull to use std::max

[traversaro]

Without this change, the z_pull_zenohc example fails on Visual Studio 2022 with the error:

The problem is that including windows.h defines the max preprocessor macro, that interferes with the subsequent use of std::max . By defining NOMINMAX , no max macros is defined.

With this and https://github.com/eclipse-zenoh/zenoh-cpp/pull/134, all the zenohc based examples compile fine on Visual Studio 2022 (xref: https://github.com/eclipse-zenoh/zenoh-cpp/issues/5), while the zenohpico one are still failing.
