This PR is motivated by #3368 and continuation of #4007

If OS has native implementation of sendfile function then it will be used (only for cmake projects).
Other projects (make and vcxporj) you can uncomment define POCO_HAVE_SENDFILE in Poco/Config.h

Note for emscripten sendfile will throw NotImplemented exception, because emscripten-core/emscripten#16234

Simple proof that this optimization is useful

Test without optimization

testFile:

OK (1 tests)

./Net-testrunner testFile  0.04s user 0.01s system 15% cpu 0.297 total

Test with optimization

testFile:

OK (1 tests)

./Net-testrunner testFile  0.03s user 0.01s system 5% cpu 0.842 total

15% vs 5%
