Moving forward dialect namespaces cannot contain '.' characters.
This cl also standardizes that operation names must begin with the dialect namespace followed by a '.'.

This reverts the previous method which needs to create a new dialect with the
constant fold hook from TensorFlow. This new method uses a function object in
dialect to store the constant fold hook. Once a hook is registered to the
dialect, this function object will be assigned when the dialect is added to the
MLIRContext.
For the operations which are not registered, a new method getRegisteredDialects
is added to the MLIRContext to query the dialects which matches their op name
prefixes.

a step forward because now every AbstractOperation knows which Dialect it is
associated with, enabling things in the future like "constant folding
hooks" which will be important for layering. This is also a bit nicer on
the registration side of things.
