[Mesa-dev] Mesa (master): lavapipe: bump maxMemoryAllocationCount

[Mike Blumenkrantz]

This is mostly to deal with zink atm because there's no
allocator/suballocator in use, meaning every resource gets its own alloc.
There's a ticket (https://gitlab.freedesktop.org/mesa/mesa/-/issues/4293)
for implementing aux/pb, but I don't have a timeline for that right now.
