Encapsulate the thread local storage into an egl::Thread class.

Instead of having separate GetGlobal* functions, interact with the global
objects through a single Thread object.  This reduces the number of TLS
lookups in many EGL functions and allows the Thread object to be passed
down to other objects if needed.
