Expose libWayland wl_display_set_default_max_buffer_size function.

[KosmX]

This is necessary to increase on higher-end systems (high polling rate hardware/high refresh-rate) to avoid crashing some apps that cannot keep up with the event loop momentarily.

For example, if a mouse has 1000 Hz polling rate (and one pointer event is 20 bytes), it takes only 200 ms to overflow the default, 4 kB buffer. This is not uncommon for an app to fail to receive events when something is loading. (personally it is an issue with Minecraft)

I need this patch upstream in Niri
