Anuj Mittal 0d052a48c9 php: add opcache extension to PACKAGECONFIG ...

OPcache improves PHP performance by storing precompiled script bytecode
in shared memory, thereby removing the need for PHP to load and parse
scripts on each request [1].

Add an option to enable opcache in php. AC_CHECK_FUNC isn't suitable for a
cross-compile environment, so pass the configure options instead to force
dlopen detection that is necessary to have extension support enabled.

On a standard phpbench test, I see a performance improvement of > 40%.
