Revert of command_buffer_gles2: Implement EGL default Display as a global object

Revert of command_buffer_gles2: Implement EGL default Display as a global object (patchset #18 id:340001 of https://codereview.chromium.org/1714883002/ )

Reason for revert:
This caused almost all GPU debug bots to fail the gles2_conform_test.

[0418/032049:FATAL:gl_surface_egl.cc(1013)] Check failed: false. Attempted to call SwapBuffers on a PbufferGLSurfaceEGL.

Original issue's description:
> command_buffer_gles2: Implement EGL default Display as a global object
>
> Make EGL Display a global. eglGetDisplay(EGL_DEFAULT_DISPLAY) will
> return the same object.
>
> Store EGL state in a new thread-local object (ThreadState). One
> display, multiple surfaces, multiple contexts.
>
> Fix the currently implemented entry points to return specified errors
> and behave as specified. Notable changes:
> * eglGetDisplay() does not create new displays for each invocation
> * eglTerminate() invalidates the created egl objects but leaves the
>   current context intact as specified
> * eglMakeCurrent() is implemented more correctly with refcount semantics
> * eglQueryStrings() works without display for some names
> * eglReleaseThread() is implemeted
> * Config are now separate for pbuffers and windows, so that contexts
>   can be created separate from surfaces
> * Context can be made current with different surfaces
> * Catches errors related to context being set current to multiple
>   threads
> * Tries to be thread-safe
>
> In the implementation, the Display contains a lock ensuring all thread
> accesses are consistent. All functions using or changing thread-local
> state have explicit egl::ThreadState parameter.

Revert of command_buffer_gles2: Implement EGL default Display as a global object
(patchset #18 id:340001 of https://codereview.chromium.org/1714883002/ )

Reason for revert:
This caused almost all GPU debug bots to fail the gles2_conform_test.

[0418/032049:FATAL:gl_surface_egl.cc(1013)] Check failed: false. Attempted to
call SwapBuffers on a PbufferGLSurfaceEGL.

Original issue's description:
> command_buffer_gles2: Implement EGL default Display as a global object
>
> Make EGL Display a global. eglGetDisplay(EGL_DEFAULT_DISPLAY) will
> return the same object.
>
> Store EGL state in a new thread-local object (ThreadState). One
> display, multiple surfaces, multiple contexts.
>
> Fix the currently implemented entry points to return specified errors
> and behave as specified. Notable changes:
> * eglGetDisplay() does not create new displays for each invocation
> * eglTerminate() invalidates the created egl objects but leaves the
>   current context intact as specified
> * eglMakeCurrent() is implemented more correctly with refcount semantics
> * eglQueryStrings() works without display for some names
> * eglReleaseThread() is implemeted
> * Config are now separate for pbuffers and windows, so that contexts
>   can be created separate from surfaces
> * Context can be made current with different surfaces
> * Catches errors related to context being set current to multiple
>   threads
> * Tries to be thread-safe
>
> In the implementation, the Display contains a lock ensuring all thread
> accesses are consistent. All functions using or changing thread-local
> state have explicit egl::ThreadState parameter.
