Add new dictionary layout (sparse_hashed) that is more memory efficient
With this new layout, sparsehash will be used over default HashMap,
sparsehash is more memory efficient but it is also slower.

So in a nutshell:
- HashMap uses ~2x more memory then sparse_hash_map
- HashMap ~2-2.5x faster then sparse_hash_map
(tested on lots of input, and the most close to production was
dictionary with 600KK hashes and UInt16 as value)

TODO:
- fix allocated memory calculation
- getBufferSizeInBytes/getBufferSizeInCells interface
- benchmarks

v0: replace HashMap with google::sparse_hash_map
v2: use google::sparse_hash_map only when <sparse> isset to true
v3: replace attributes with different layout
v4: use ch hash over std::hash

e1898ca89a Make the quadratic Arena::allocContinue less bad.
Scenarios that use Arena::allocContinue may waste quadratically many
memory and perform quadratically many copying, when the memory range
size reaches Arena's linear allocation threshold. To alleviate this,
make sure that the next memory chunk allocated by allocContinue is at
least linear_growth_threshold bytes bigger than the previous one, so
that we don't reallocate and copy that often.
