[roll third_party/pigweed] pw_rpc: Locking improvements
- Expand locking annotations for internal::Call class members.
- Have the ChannelOutput::Send call release the RPC lock right before
sending the packet. This ensures the Call object's OutputBuffer
reference is cleared while the lock is held.
- Avoid holding the RPC lock while logging.
- Clear the encoding buffer in FakeChannelOutput to catch code that
uses stale references.
- Have FakeChannelOutput check that its buffers are properly acquired
and released.
- Mark PayloadBuffer() as [[nodiscard]].
