new APCu setup check

We have a new setup warning to check if the memory reserved for APCu is high enough. If you see this warning, you should increase the memory reserved for APCu. You can do this by increasing the value of the apc.shm_size directive in your php.ini file. It is generally advised to review this value and increase it if necessary depending on your instance size.

Talk high performance backend (HPB) check

No High-performance backend configured - Running Nextcloud Talk without the High-performance backend only scales for very small calls (max. 2-3 participants). Please set up the High-performance backend to ensure calls with multiple participants work seamlessly.
