This adds the capability to report exceptions from both ResourceManagerIO and
ResourceManagerSTM, further increasing feature parity.

Adds a timeout to the root resource manager before exceptions are logged
to the console (usually they are thrown as a CombinedException, so
logging is only required for debugging visibility when resource
management is deadlocked).

Since creating and attaching resources was already possible from STM,
removing the MonadAwait/MonadIO/MonadMask-constraints from
MonadResourceManager is the primary change in this commit.

This reduces awaitable back to a simple newtype wrapper over the STM
monad. While caching worked well, it was only applicable in very few
situations. Based on the high complexity, the rare use cases and the
negative interaction with STM we decided to remove caching.
