Add adapter LUID to EGL vendor string.

Add adapter LUID to EGL vendor string.

This is so Chrome can create another D3D device on the same adapter that can share resources with ANGLE's D3D device.

Here is the eglQueryString way to get the LUID as discussed. Thx!

File src/libEGL/Display.cpp (right):

https://codereview.appspot.com/9225046/diff/1/src/libEGL/Display.cpp#newcode1258
src/libEGL/Display.cpp:1258: sprintf_s(adapterLuidString,
sizeof(adapterLuidString), "%08x%08x", adapterLuid.HighPart,
adapterLuid.LowPart);
This could include the " LUID:" part as well, so you don't have to add it
separately below.

I also suggest to be a little more verbose to avoid confusing other people who
query this string. For instance use "Google Inc. (adapter LUID: %08x%08x)". I
added round brackets to make it similar to the GL_VERSION format and make it
clear that it is non-essential information).

Done. PTAL.
