Add build targets for advanced Intel instruction sets (1.5 of 3)
This is a follow-up to https://codereview.chromium.org/1290423007/,
with a couple small changes:
- turn on AVX and AVX2 for Windows using /arch ('EnabledEnhancedInstructionSet')
- reformat and de-conditionalize where possible / irrelevant
Picked up this while poking around in libvpx's Chrome GYPs.
And yes, AVX = 3, AVX2 = 5. Don't even ask what 4 means...
