Address Sanitiser in MSVC incorrectly identifies a non-virtual destructor, but the class is not polymorphic

When built with Address Sanitiser, the engine can except in FShaderPipeline::FindOrAddShader on deletion of the Shader pointer.
This appears to be in error as FShader is asserted to be non-polymorphic.

This may ultimately be an MSVC ASAN issue, though I thought it worth bringing attention to as ASAN appears to able to be instructed to skip analysis of certain functions or variables.
