Sarah Spall 5999988af8 [HLSL] Move where ZExt happens in 'EmitStoreThroughExtVectorComponentLValue' to handle bug with hlsl boolean vector swizzles (#140627) ...

In 'EmitStoreThroughExtVectorComponentLValue', move the code which ZExts
in the case the Destination Scalar Type is larger than the Source Scalar
Type, to the top of the function, to ensure each condition is handled.

The previous code missed this case:
```
bool4 b = true.xxxx;
b.xyz = false.xxx;
```
Leading to a bad shuffle vector. 

Closes #140564
