[Matrix] Implement matrix support for the `clamp` HLSL Function

> Note: This issue tracks matrix support for `clamp`. The original implementation issue is [here](https://github.com/llvm/llvm-project/issues/70071).

Matrix requirements:
- [ ] https://github.com/llvm/wg-hlsl/issues/387

## HLSL:
Clamps the specified value to the specified minimum and maximum range.

## Parameters

| Item | Description |
|--------------------------------------------------------------|------------------------------------------------|
| *x*
| \[in\] A value to clamp.
|
| *min*
| \[in\] The specified minimum range.
|
| *max*
| \[in\] The specified maximum range.
|

## Return Value

The clamped value for the *x* parameter.

## Remarks

For values of -INF or INF, clamp will behave as expected. However for values of NaN, the results are undefined.

## Minimum Shader Model

This function is supported in the following shader models.

| Shader Model | Supported |
|------------------------------------------------------------------------------------|-----------------------|
| [Shader Model 2 (DirectX HLSL)](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-sm2.md) and higher shader models | yes |
| [Shader Model 1 (DirectX HLSL)](https://github.com/MicrosoftDocs/win32/blob/docs/desktop-src/direct3dhlsl/dx-graphics-hlsl-sm1.md) | vs\_1\_1 and ps\_1\_4 |

Start with the original implementation issue #70071 and review the linked matrix requirement in wg-hlsl issue #387. Use the HLSL clamp type table in this issue to define the supported matrix cases; done means matrix inputs, minimums, maximums, and return values are supported consistently with the stated dimensions.
