In refactoring described in #7211, the implementation of #maxInboundMessageSize(int)
(and its corresponding field) was pulled down from internal AbstractManagedChannelImplBuilder
to concrete classes that actually enforce this setting. For the same reason, it wasn't ported
to ManagedChannelImplBuilder (the #delegate()).

Then AbstractManagedChannelImplBuilder was brought back to fix ABI backward compatibility,
and temporarily turned into a ForwardingChannelBuilder, ref PR #7564. Eventually it will
be deleted, after a period with "bridge" ABI solution introduced in #7834.

However, restoring AbstractManagedChannelImplBuilder unintentionally made ABI of
#maxInboundMessageSize(int) implemented by the concrete classes backward incompatible:
pre-refactoring builds expect it to be a method of AbstractManagedChannelImplBuilder,
and not concrete classes, ref #8313.

The end goal is to keep #maxInboundMessageSize(int) only in concrete classes that enforce it.
To fix method's ABI, we temporary reintroduce it to the original layer it was removed from:
AbstractManagedChannelImplBuilder. This class' only intention is to provide short-term
ABI compatibility. Once we move forward with dropping the ABI, both fixes are no longer
necessary, and both will perish with removing AbstractManagedChannelImplBuilder.


Tested manually by reproducing #8313, then confirming this PR fixes it.

This is an alternative to #8597
Fixes #8313

Ah, yes. This is definitely better than my #8597. It just converts back to the way it was, but still with the new way of doing things.
