misc: Add vkGetInstanceProcAddr() entrypoint

Adding this entrypoint as this has been discussed in khronos  and is needed
for the loader/layer/extension proposal.

Caveats:
1) Have not updated layers or any tests/demos yet that will come later;
2) No one including loader is using this call yet;
3) Leaving exisitng vkGetProcAddr() as is for now; later once loader
is using vkGetInstanceProcAddr call can switch vkGetProcAddr() to
vkGetDeviceProcAddr()
