[Core] Use New Router (#3584)

This updates LORIS to use the PSR15 RequestHandler/Middleware based router that was implemented in PRs #3477, #3480, and #3513.

Most of the mod_rewrite rules, main.php, and NDB_Caller are replaced by a new index.php, which generates a PSR7 ServerRequestInterface and delegates to the module's Module handler.

AjaxHelper.php remains, but is deprecated, as existing scripts will need to be updated to be proper endpoints in the module's router. (Once this is done, the separate router.php for PHP's built in web server can also be removed, and mod_rewrite dependency for LORIS can be removed.)

main.php and NDB_Caller also remain for now in order to load instruments. Once an instrument module is implemented to handle the instruments routers, they can be removed.

Note that instrument URLs also change from $LORIS/instrumentname to $LORIS/instruments/instrumentname as part of this change.
