Simplify gettimeofday() fallback logic.
There's no known supported system needing 1 argument gettimeofday()support. The test for it was added a long time ago (92c6bf9). Remove.Until now we tested whether a gettimeofday() fallback is needed whentargetting windows. Which lead to the odd result that HAVE_GETTIMEOFDAY onlybeing defined when targetting MinGW (which has gettimeofday() since at least2007). As the fallback is specific to msvc, remove the configure code andrename src/port/gettimeofday.c to src/port/win32gettimeofday.c.While at it, also remove the definition of struct timezone, a forwarddeclaration of the struct is sufficient.Reviewed-By: Tom Lane <tgl@sss.pgh.pa.us>Reviewed-By: Thomas Munro <thomas.munro@gmail.com>Discussion:https://postgr.es/m/20220806000311.ywx65iuchvj4qn2k@awork3.anarazel.de
