[mlir][tblgen] Add PredTypeTrait/PredAttrTrait support (#169153)

This patch adds support for `PredTypeTrait` and `PredAttrTrait` in type
and attribute definitions, enabling declarative predicate-based
verification similar to how `PredOpTrait` works for operations.

  ## Motivation

In 802bf02 (from 2021), `PredTypeTrait`/`PredAttrTrait` were defined in
TableGen but not implemented in the code generator. Using them causes
mlir-tblgen to crash with an assertion failure when trying to cast
`PredTrait` to `InterfaceTrait`. This patch fixes the crash and
implements the actual verification code generation.

  ## Usage

Use `$paramName` syntax in predicates to reference type/attribute
parameters:

  ```tablegen
  def MyType : MyDialect_Type<"MyType",
      [PredTypeTrait<"value must be positive", CPred<"$value > 0">>]> {
    let parameters = (ins "unsigned":$value);
    let mnemonic = "my_type";
    let assemblyFormat = "`<` $value `>`";
  }
  ```

  This generates verification code in `verifyInvariantsImpl()`:
```cpp
  if (!(value > 0)) {
    emitError() << "failed to verify that value must be positive";
    return ::mlir::failure();
  }
  ```
