Commit Message

core: add panic mode for ManagedChannelImpl (#4023)

Channel enters this mode whenever there is an uncaught throwable from
its ChannelExecutor, which is where most channel internal states are
mutated, such as load-balancing.

In panic mode, the channel will always report TRANSIENT_FAILURE as its
state, and will fail RPCs with an INTERNAL error code with the
uncaught throwable as the cause, which is helpful for investigating
bugs within gRPC and 3rd-party LoadBalancer implementations.

## Change to existing behavior
Previously if `LoadBalancer` throws in `handleResolvedAddressGroups()`, it would
be routed back to `LoadBalancer.handleNameResolutionError()`. Now it will make
the channel panic.

## Internal refactors
- Refactored out `shutdownNameResolverAndLoadBalancer()`, called from three code paths: `enterIdleMode()`, `delayedTransport.transportTerminated()`, and `panic()`.
- Refactored out `updateSubchannelPicker()`, called from both `updateBalancingState()` and `panic()`.
