RFC: https://discourse.llvm.org/t/rfc-a-poly-dialect-for-polynomial-arithmetic/73891

This PR implements the minimal work needed to represent the polynomial type such that it can be tested with `lit`.

Please let me know if this PR is too big to review, and I can split it into smaller pieces:

- Dialect shell
- `Polynomial` storage type
- Polynomial attributes (`PolynomialAttr` and `RingAttr`)
- `polynomial.polynomial` type

Note that I also have C++ unit tests for the polynomial storage type that can be ported from https://github.com/google/heir/blob/main/lib/Dialect/Polynomial/IR/PolynomialTest.cpp, if desired. I believe C++ unit tests are considered less preferred than `lit` tests, but let me know if you prefer unit tests on top of lit tests.

+    A ring describes the domain in which polynomial arithmetic occurs. The ring
+    attribute in `polynomial` represents the more specific case of polynomials
+    with a single indeterminate; whose coefficients can be represented by
+    another MLIR type (`ctype`); and, if the coefficient type is integral,
+    whose coefficients are taken modulo some statically known modulus (`cmod`).
+
+    Additionally, a polynomial ring can specify an _ideal_, which converts
+    polynomial arithmetic to the analogue of modular integer arithmetic, where
+    each polynomial is represented as its remainder when dividing by the
+    modulus. For single-variable polynomials, an "ideal" is always specificed
+    via a single polynomial, which we call `polynomialModulus`.
+
+    An expressive example is polynomials with i32 coefficients, whose
+    coefficients are taken modulo `2**32 - 5`, with a polynomial modulus of
+    `x**1024 - 1`.
+
+    ```

+
+    %0 = ... : polynomial.polynomial<#ring>
+    ```
+
+    In this case, the value of a polynomial is always ``converted'' to a
+    canonical form by applying repeated reductions by setting `x**1024 = 1`
+    and simplifying.
+
+    The coefficient and polynomial modulus parameters are optional, and the
+    coefficient modulus is only allowed if the coefficient type is integral.

+    The Polynomial dialect defines single-variable polynomial types and
+    operations.
+
+    The simplest use of `polynomial` is to represent mathematical operations in
+    a polynomial ring `R[x]`, where `R` is another MLIR type like `i32`.
+
+    More generally, this dialect supports representing polynomial operations in a
+    quotient ring `R[X]/(f(x))` for some statically fixed polynomial `f(x)`.
+    Two polyomials `p(x), q(x)` are considered equal in this ring if they have the

+    are performed with reductions modulo `f(x)` and relative to the coefficient ring
+    `R`.
+

+
+    ```mlir
+    // A constant polynomial in a ring with i32 coefficients and no polynomial modulus
