Refactor AC_INIT in configure.ac and PHP versions

Since Autoconf 2.53 the AC_INIT call with only a single argument has
been made obsolete and now includes several other optional arguments to
make installation experience a bit better by providing program version
and links to the project in the `./configure -h` output. This patch also
updates win build version. The phpize.m4 AC_INIT has been updated with
the call without arguments.
