wip: Remove memory and upload PHP settings

Because memory & file size limitation settings are specified in the local configs, they override any
values in the global `php.ini` on the system. Because of this, it's impossible to, for example,
increase the memory limit of Nextcloud without touching its own configuration/source files.

These settings are removed in favor of the `php.ini` settings. The justification for not having
these settings specified strictly by Nextcloud is that they are variant. In other words, their
values are environment-dependent, and especially dependent on the content hosted by Nextcloud
itself. For example, hosting lots of images and thumbnails frequently causes memory issues.
