crimson/osd: make the ObjectContextRegistry per-PG

This patch moves the OBC registry from ShardServices (which
is basicaly a gateway to a bunch of PGs) into PG itself.
Dividing OBCs by PG (they truly belong to) minimizes the space
to search when e.g. checking whether a client is blocked or
not. Therefore, this commit is enabler of more performant
PR #47637.

The changeset draws the assumption that OBC registry and all
its users live on the same CPU core. It looks valid to me.

crimson/net: refactor socket managements

Previously, the socket state is transparent to the protocol and
implicitly handled. Move the responsibilities into protocol for finer
controls to further decouple the IO and handshake.

Also, refactor the fault handling and make the in/out message
dispatching more symmetric.

crimson/net: introduce and integrate FrameAssemblerV2

FrameAssemblerV2 encapsulates the low-level frame processing for

FrameAssemblerV2 is supposed to be running on the socket core for
performance reasons, which will be changable.
