Widen color state support on ES.

Indexed draw buffer (color state) support on ES is not core until 3.2.
Previously, we were failing (asserting) if color state was changed for
a non-zero attachment. This CL compares the state, and only asserts if the
color state actually differs per-attachment.

It also implements a disable_indexed_draw_buffers toggle, which allows a
test to check for the functionality in a platform-independent manner.
