[mlir][Transforms] Dialect Conversion: `allowPatternRollback` to check foldings (#148394)
When an operation is folded to an attribute, the attribute must be
materialized as a constant operation. That operation must then be
legalized. If such a legalization fails, the entire folding is rolled
back. This is not supported in a One-Shot Dialect Conversion. (Support
for rolling back foldings could be added at a later point of time.)
This commit improves the `allowPatternRollback` flag handling, such that
a fatal error is reported when a folder is attempted to be rolled back.
