Robert Bragg b8e380edc3 gpu-info: Detect more info including architecture
The GPU info api previously told us a driver package name and a driver
vendor name, but now we have introduced detection for the gpu
architecture too and started to track architecture feature flags that
can tell us whether a gpu is a deferred or immediate mode renderer for
example or if a software rasterizer is being used.

This also adds support for checking more vendor names. We should now
detect the following cases:

Vendors: Intel, Imagination Technologies, ARM, Qualcomm, Nvidia, ATI
Architectures: Sandybridge, SGX, Mali
Architecture flags:
  - vertex tiled
  - vertex immediate mode
  - vertex software
  - fragment deferred
  - fragment immediate mode
  - fragment software
