staging: erofs: introduce generic decompression backend
This patch adds a new generic decompression framework
in order to replace the old LZ4-specific decompression code.
Even though LZ4 is still the only supported algorithm, yet
it is more cleaner and easy to integrate new algorithm than
the old almost hard-coded decompression backend.
