Subject: [PATCH] Increase MAX_COMPRESSED_STATE_WITNESS_SIZE to 48 MiB (#11683)

The `MAX_COMPRESSED_STATE_WITNESS_SIZE` has been set to 32 MiB in
https://github.com/near/nearcore/pull/11511. Back then it was a
reasonable choice, but since then we increased some of the runtime
parameters, which increased the worst case witness size by ~17MiB.
(https://github.com/near/nearcore/pull/11582,
https://github.com/near/nearcore/pull/11629). I'd feel safer with a
larger limit on the compressed witness size.
