New experiments.incremental

We are implementing a new incremental rebuild architecture that makes the HMR much faster. It's an experimental feature in v1.1 and we still have more work to do before we stabilize it, but for now we have implemented parts of it and seen significant performance boosts.

In a case of 10000 React components, the HMR becomes 38% faster:

Faster output.hashFunction

Rspack's output.hashFunction now defaults to the faster xxhash64, and the output.hashDigestLength now defaults to 16 (prev 20).

In the very large projects, this change will bring a significant performance improvement:

hyperfine --warmup 1 --runs 3 'HASH_FUNCTION=md4 node --run build:rspack' 'HASH_FUNCTION=xxhash64 node --run build:rspack'
Benchmark 1: HASH_FUNCTION=md4 node --run build:rspack
  Time (mean ± σ):     11.428 s ±  0.758 s    [User: 83.504 s, System: 5.808 s]
  Range (min … max):   10.892 s … 12.295 s    3 runs

Benchmark 2: HASH_FUNCTION=xxhash64 node --run build:rspack
  Time (mean ± σ):      9.697 s ±  0.318 s    [User: 79.664 s, System: 6.127 s]
  Range (min … max):    9.374 s … 10.009 s    3 runs

Summary
  HASH_FUNCTION=xxhash64 node --run build:rspack ran
    1.18 ± 0.09 times faster than HASH_FUNCTION=md4 node --run build:rspack
