ui/gl: rename ClearGLBindings to ShutdownGL

ui/gl: rename ClearGLBindings to ShutdownGL

When initializing ui/gl, the GL bindings are first populated, then the
PlatformOneOff initialization is done. ClearGLBindings is currently
used by tests and the vr_shell to completely deinit the GL, not just
clearing the bindings. Rename it accordingly.

kbr: PTAL, this is the renaming for https://codereview.chromium.org/2491993002

thakis, bajones, liberato: this rename touches some Ozone, VR and Android media
files, PTAL

[liberato (no reviews please), 2016-12-02 21:00:33]

media/ lgtm.

[Nico, 2016-12-02 21:02:51]

rs-lgtm if kbr likes this.

(Note: There's talk every now and then to remove "shutdown" activity from chrome
and just kill the process when it's time to close. So if this call is needed
outside of tests, you might want to leave a comment somewhere explaining why
someone looking through the codebase for "shutdown" stuff to remove might not
want to delete this one)
