Implement a hash map that lives in shared memory, with a custom allocator
Summary:
Implement a hash map that lives in shared memory, using a dedicated bump allocator to allocate memory.
- We use hashbrown's `HashMap` as the underlying hash map implemention.
- The underlying allocator is a simple bump allocator which allocates chunks of 10 MiB from an underlying file allocator (introduced in a previous diff)
