A Proper lookup table that uses HashTable's API

This is the first step of allowing heterogeneous cells in hash tables.
performance test results are
```
1. HashMap<UInt16, UInt8, TrivialHash, HashTableFixedGrower<16>>;
2. NewLookupMap<UInt16, UInt8>

Support xxHash with external lz4
...
xxhash.h does not exist in external lz4 because it is an implementation detail
and its symbols are namespaced with XXH_NAMESPACE macro. When lz4 is external,
xxHash has to be external too, and the dependents have to link to it.
This find_xxhash.cmake is based on find_lz4.cmake.
