OpenGL: Remove all attachments before executing internal clear This patch fixes a bug in BlitGL::clearRenderbuffer() by removing all the attachments of mScratchFBO before attaching the real target of clear to keep mScratchFBO always being incomplete. Without this fix, the WebGL CTS tests mentioned in issue 2760 will fail on Intel OpenGL drivers when Chromium is using pass through command buffer because when a multisampled depth renderbuffer is attached to mScratchFBO, mScratchFBO will sometimes become incomplete because it may already have a non-multisampled color attachment.
