[mlir] Move memref-tests from standard to memref folder.

[dfki-thsc]

Summary

Split memref-test from standard test and move them to the folder MemRef.

Thank you for cleaning this up, Thomas!

(On Diff #339209)

I guess the transformation memref.reshape -> memref.reinterpret_cast also has to move to MemRef/Transforms directory. Also we need MemRefToLLVM pass decoupled from Std. Definitely, not in this PR.
