cc: Fixing scheduler state machine tests around BeginMainFrameAborted.

This CL does the following;
 1) TestGoesInvisibleBeforeFinishCommit -> TestAbortBeginMainFrameBecauseInvisible
 2) AbortBeginMainFrameAndCancelCommit -> TestAbortBeginMainFrameBecauseCommitNotNeeded
 3) AbortBeginMainFrameAndCancelCommitWhenInvisible -> removed (duplicate of 1.)
 4) AbortBeginMainFrameAndRequestCommitWhenInvisible -> removed (duplicate of
      TestNoCommitStatesRedrawWhenInvisible and TestRequestCommitInvisible)

When BeginMainFrameAborted is called with **false** it means we **didn't**
attempt a commit. Any pending commits are "not satisfied" and should still be
pending afterwards.

When BeginMainFrameAborted is called with **true** it means we attempted the
commit but there was no work to do. Any pending commits been have been
"satisfied" and should **not** be pending afterwards.

Looking at the code in ThreadProxy::BeginMainFrame method we can confirm this
is the case,

TRACE_EVENT_INSTANT0("cc", "EarlyOut_NotVisible", TRACE_EVENT_SCOPE_THREAD);
 Which calls BeginMainFrameAborted(false);

TRACE_EVENT_INSTANT0("cc", "EarlyOut_OutputSurfaceLost", TRACE_EVENT_SCOPE_THREAD);
 Which calls BeginMainFrameAborted(false);

TRACE_EVENT_INSTANT0("cc", "EarlyOut_NoUpdates", TRACE_EVENT_SCOPE_THREAD);
 Which calls BeginMainFrameAborted(true);
