samlightfoot a2feb9ffe6 Release Jackson BufferRecycler to its pool in encoders ...

Both encoders acquire a pooled BufferRecycler via
factory._getBufferRecycler() but never return it. Jackson 3 changed the
default pool from a ThreadLocal to a per-factory ConcurrentDequePool that
only refills on an explicit releaseToPool(), so the gap leaves the pool
empty and every encode allocates a fresh recycler and buffers.

Hold the recycler in a local and release it once the generator and byte
builder are done: in encodeValue's finally, and in the streaming path's
doAfterTerminate after generator.close() and byteBuilder.release().
releaseToPool() is idempotent, so sharing the recycler with the generator
cannot double-release.

Closes gh-37059
