[CmdPal][AOT] Using ExprTk to make the Cal extension AOT-compatible (#39972)

<!-- Enter a brief description/summary of your PR here. What does it
fix/what does it change/how was it tested (even manually, if necessary)?
-->
## Summary of the Pull Request
This PR replaces the original Mages-based expression evaluation engine
with a WinRT-wrapped version of Exprtk in the CmdPalCalculator module.

### Key Changes
**Expression Engine:**

- All expression parsing and evaluation now use Exprtk (via a WinRT
wrapper) instead of Mages.

**Base Conversion Handling:**

- Since Exprtk does not support non-decimal (binary, octal, hexadecimal)
input natively, added logic to convert all such inputs to decimal before
evaluation.

**Code Structure:**

- The overall logic and API surface remain unchanged except for the
engine and base conversion handling.
- All previous Mages references and dependencies have been removed.

+# C++/WinRT CalculatorEngine Project Overview
+
+This project wraps the exprtk expression parsing library with a C++/WinRT component,  
+making advanced mathematical evaluation capabilities available to Windows applications.  
+It is designed specifically to provide calculation support for the CmdPal calculator extension.
+
+## Using exprtk
+
+This project uses [exprtk](https://github.com/ArashPartow/exprtk) as the 
+expression parsing and evaluation engine.
+
+How to use exprtk in this project:
+- The exprtk header file (`exprtk.hpp`) is included in the project source.
+- You can use exprtk to parse and evaluate mathematical expressions in your 
+  C++ code. For example:
+
+    ```cpp
+    #include "exprtk.hpp"
+    exprtk::expression<double> expression;
+    exprtk::parser<double> parser;
+    std::string formula = "3 + 4 * 2";
+    parser.compile(formula, expression);
+    double result = expression.value();
+    ```
+
+How to update exprtk:
+1. Download the latest `exprtk.hpp` from the [official repository](https://github.com/ArashPartow/exprtk).
+2. Replace the existing `exprtk.hpp` file in the project with the new version.
+3. Rebuild the project to ensure compatibility and take advantage of any updates.
