*Steps to reproduce:*

1. Create a new unlit shader
2. Put the following code in the fragment function:
```
int x[3][3][3] = {
{ { -1, -2, -1 }, { -2, -4, -2 }, { -1, -2, -1 } },
{ { +0, +0, +0 }, { +0, +0, +0 }, { +0, +0, +0 } },
{ { +1, +2, +1 }, { +2, +4, +2 }, { +1, +2, +1 } }
};
half4 col = tex2D(_MainTex, i.uv);
return col * half4(x[0][0][0], x[1][1][1], x[2][2][2], 1.0);
```
3. Inspect the shader code compiled for GLES3 (same code is used for Vulkan and WebGL/WebGPU).

*Actual results:* 
The data from the array 'x' gets stored as floats using 'intBitsToFloat', then gets converted back to int using 'floatBitsToInt', then gets converted to float using the regular cast.
*Expected results:* 
No interim conversions between bit representations happen.

*Reproducible with versions:* 
2024.1, 2023.3, 2023.2, 2022.3, 2021.3
