[mlir] Add isa/dyn_cast support for dialect interfaces

Authored by rriddle on Jan 21 2022, 12:38 AM.



This matches the same API usage as attributes/ops/types. For example:

Dialect *dialect = ...;

// Instead of this:
if (auto *interface = dialect->getRegisteredInterface<DialectInlinerInterface>())

// You can do this:
if (auto *interface = dyn_cast<DialectInlinerInterface>(dialect))
