Add opcache_preloading() internal function
Add a C function, opcache_preloading(), that returns true during preloading. Extensions can use this to detect preloading, not only during compilation/execution, but also in RINIT()/RSHUTDOWN(). Since opcache currently doesn't install any header, I'm adding a new one: zend_accelerator_api.h. Header name is based on other files in ext/opcache. Closes phpGH-19288
