i965: Stop abusing ctx->NewState flags for storing driver internal changes.

We're still abusing the flags by putting them where our driver stores
ctx->NewState changes.  Making them into more restricted state change
flags would be a project for later.

Fixes a failure where calling intel_draw_buffer() too often would trip
up Mesa assertions about when Mesa state could get changed, when it hadn't.

Bug #27034.
