Upgrade/Install: Invalidate OPcache for PHP files during updates.

When files are copied into place, check whether opcode invalidation is available and attempt to invalidate to avoid unintended behavior or fatal errors from themes, plugins, or core.

Introduces wp_opcache_invalidate() to allow safe invalidation of PHP files from opcode cache, and a filter, wp_opcache_invalidate_file to override the behavior.

Replaces the existing calls to opcache_invalidate() in the plugin and theme editors to use the new function.

Thanks to jnylen0 for porting over a patch from ClassicPress that provided much of the approach for what is being committed.
