Proposal to move the `-test-transform-dialect-erase-schedule` pass into the Transform dialect itself.

[paul0403]

After running -transform-interpreter, a useful pass to have is removing all the transform dialect operations from an mlir. Currently there is only a test pass that does this:

llvm-project/mlir/test/lib/Dialect/Transform/TestTransformDialectInterpreter.cpp

Line 31 in 0891ccc

return "test-transform-dialect-erase-schedule";

It would be really nice to have this pass in the Transform dialect properly, say alongside the -transform-interpreter here https://github.com/llvm/llvm-project/blob/0891ccc0c68c35e17562c752955788f08054bcdb/mlir/include/mlir/Dialect/Transform/Transforms/Passes.td

I imagine this would be a very useful quality-of-life update.
