LOG: [mlir][NFC] Move the operation interfaces out of Analysis/ and into a new Interfaces/ directory.

The interfaces themselves aren't really analyses, they may be used by analyses though. Having them in Analysis can also create cyclic dependencies if an analysis depends on a specific dialect, that also provides one of the interfaces.
