Mechanically replace Shadow DOM v0 with v1 in web_tests [CL 2 of 3]

This CL is the result of the following mechanical replacements, within
the third_party/blink/web_tests folder, on only .html and .js files:

'.createShadowRoot()'               -> '.attachShadow({mode: 'open'})'
'document.createElement('content')' -> 'document.createElement('span')'

Several web_tests did not pass after the above replacements were made.
Those tests were reverted - the changes in this CL are only the tests
that pass in the same way that they did prior to the replacements.
The only exceptions, which were re-baselined here, had *only* a
console warning message like this, which is now missing:

CONSOLE WARNING: line 27: Element.createShadowRoot is deprecated
and will be removed in M80, around February 2020. Please use...

In addition, most of the same test expectations files were completely
removed from the virtual/web-components-v0-disabled folder, since these
tests no longer depend on WCv0 features, and no longer fail.
