[mlir][Transforms][NFC] Dialect Conversion: Move `lookup` functions (#150743)

Add `lookupOrDefault` / `lookupOrNull` wrappers to
`ConversionPatternRewriterImpl` and call those wrappers throughout the
code base.

This commit is in preparation of the One-Shot Dialect Conversion
refactoring. In future, the implementation will bypass the `mapping`
when rollback is disabled. The switch will be made in those wrapper
functions.
