[MLIR] Remove deprecated setting usePropertiesForAttributes (#182327)
This was slotted for removal in LLVM 19 in the release notes of LLVM 17,
we're way past it now.
If your dialect still has:
> let usePropertiesForAttributes = 1;
Then you can just remove this line (it was the default value).
If you were setting it to 0:
> let usePropertiesForAttributes = 0;
Then you need to adopt the new behavior, please report any issue with
this migration.
