Native: don't build tests/samples/echoServer on Windows

Because of KT-50547, this test doesn't work on Windows with HMPP
enabled.

Previously, because of that HMPP was disabled for all samples.
But now disabling HMPP is no longer possible, so ce9a45b enables HMPP
for samples.

Disable echoServer sample on Windows to workaround ^KT-50547
