Split up LibAFL-bolts into reusable libraries

We have a bunch of cool libs hidden inside libafl-bolts.
Let's break them apart for people to use individual components outside of libafl more easily.

In general, I propose the following libs (renamed according to crates.io name availability), with descriptions:

`shmem`: Shared Memory support for Windows, Linux, MacOS, *nix
`signal-handler`: exception handling library for raw &unsafe exception/crash handling
`fast-rands`: Non-cryptographically secure (but fast) RNGs
`anymap`: Map to store and retrieve types, SerDe compatible
`build_id2`: Updated and maintained build id library
`core_affinity2`: Updated and maintained core_affinity library with larger OS support
`llmp`: Low-level message passing: A lockfree IPC library for many-to-one - one-to-many messages
`minibsod`: Write stack traces on crashes
`ownedref`: Wrappers that abstracts references (or pointers) and owned data accesses, that deserialize to owned values
`tuple_list_ex`: Additional methods for compiletime tuple_lists
`libafl-simd`: SIMD acceleration
`libafl-bolts`: all the rest
