[mlir] Fix gcc -std=c++17 compilation.

[Meinersbur]

Summary

Ensure that Handler within the class is interpreted as the as the current template instantiation (instead the class template itself).

Fixes #53447

Thanks!

Nit: if you type in the description Fixes #53447 then it'll close the issue automatically and link the commit to the issue on GitHub.

I think this broke the windows mlir bot: https://lab.llvm.org/buildbot/#/builders/13/builds/17954/steps/6/logs/stdio

Note, it may not be this change, but another related change. The bot was offline for a few days because of a different issue.
