gl_device: Block async shaders on AMD and Intel

Currently, the Windows versions of the Intel OpenGL driver and the AMD
proprietary OpenGL driver do not properly support (or in fact degrade)
when asynchronous shader compilation is enabled. This blocks
specifically those drivers from using this feature. This affects
AMDGPU-PRO on Linux, and AMD's and Intel's OpenGL drivers on Windows.
