Using #pragma require in .raytrace files doesn't work. All pragma require directives are ignored.

Steps to reproduce:

1. Clone the project from [https://github.com/INedelcu/PathTracingDemo] and open Assets/Shaders/RayGenerator.raytrace

2. Use one of the pragma require in a .raytrace file for example #pragma require int64bufferatomics or #pragma require int64 and save the file.

3.  The shader fails to compile and generates the following error: 
{quote}opcode '64-bit atomic operations' should only be used in 'Shader Model 6.6+'.{quote}

Actual results: No shader compilation errors are generated when using #pragma require directives.

Expected results: Shader fails to compile.
