I observed allocation becoming a bottleneck when building the depsgraph with scenes with many simple data-blocks. One of the main culprits was the struct that encodes relations between nodes in the graph. Instead of allocating each `Relation` with a separate allocation call, combine them into a `LinearAllocator`. That is must faster because it allocates in large chunks and just bumps an offset on each allocation. In a test file with 30 thousand cube objects, I observe a 1.18x improvement in depsgraph evaluation time, from 1370 to 1163 ms. The depsgraph isn't completely re-allocated when it's rebuilt, so the allocator added in this PR has to be cleared manually. In the future, it can be used for other structs or potentially strings.
