Implement GL_EXT_color_buffer_half_float.

This exposes previously enabled functionality. Also update the format support check to be: supported: GLES3 || texture extension renderable: supported && color buffer extension filterable: filtering extension (Note: we silently support float rendering in ES2) BUG=angleproject:1229 Change-Id: Icf0775891d6e336acd1a0ac07c3b37cf6bb0f101 Reviewed-on: https://chromium-review.googlesource.com/308430 Tryjob-Request: Jamie Madill <jmadill@chromium.org> Reviewed-by: 's avatarCorentin Wallez <cwallez@chromium.org> Reviewed-by: 's avatarGeoff Lang <geofflang@chromium.org> Tested-by: 's avatarJamie Madill <jmadill@chromium.org>
