ANGLE: Support WinRT

This enables EGL for WinRT's native types, and adjusts some codepaths
to accommodate differences in between desktop Windows and WinRT.

- WinRT native handles added to eglplatform.h
- References to native handles in libEGL/libGLESv2 follow eglplatform.h
- D3D 11.1 structures and methods used when necessary
- TLS replaced with thread attribute
- LocalAlloc/Free replaced with Heap API
