This commit implements the `uffd` feature which turns on support for utilizing the `userfaultfd` system call on Linux for the pooling instance allocator. By handling page faults in userland, we are able to detect guard page accesses without having to constantly change memory page protections. This should help reduce the number of syscalls as well as kernel lock contentions when many threads are allocating and deallocating instances. Additionally, the user fault handler can lazy initialize linear memories of an instance (implementation to come).
