Split up mixed content devtools test into 3 separate tests

Split up mixed content devtools test into 3 separate tests

When testing all three mixed content types in one test, the test was
flaky because DevTools received requestWillBeSent events in different
orders. Instead of making sure that the requests are always sent in the
same order, this CL splits up the test into 3 separate tests, one for
each mixed content type, with common code in
resources/mixed-content-type-test.js.

pfeldman: PTAL? This simplifies the mixed content devtools test by splitting it
into 3 tests (one for each type of mixed content), with common code in
resources/mixed-content-type-test.js.

If you prefer to keep it all in one test, then I think we have to go back to
something like I had in patchset #4 of
https://codereview.chromium.org/1299493003, where onRequestWillBeSent() keeps
track of the state and decides when to transition to the next test case (to
guarantee that the requests get sent in the same order every time).
