MinGW: Remove old workaround and use native echo (#12283)

The workaround added by commit 7e92f0b4 (Hack to make echo command work
properly in mingw32-make, 2006-10-05) and updated by commit 69356d8a
(Juse use cmake -E echo instead of the native echo, 2006-10-13) no
longer seems necessary with modern mingw32-make.  Furthermore it slows
performance due to the time spent loading a cmake process instead of
plain echo.
