This includes some major internal changes that should improve performance (the AOT template compiler) and the new lookup code. The big changes noticeable for Flutter will be resolution of field formal parameters, extension method support, and more consistent disambiguation in comment reference lookups.

While a vast net improvement, this PR will change a few links to point to the wrong place. #85484 will address that after this lands, as there was no good way to specify what the user wanted unambiguously before dartdoc 1.0.0 in a few cases. That PR includes more details on the introduced regressions and link changes.

This turns on order shuffling for all tests that don't fail with it on, marking those tests that do fail with a tag so that they will be run without shuffling on.

To determine which tests fail with it on, I ran all the tests 100 times with different random shuffle seeds, and then also ran it with the date seeds from today until the end of July, and tagged all of the test suites (files) that fail, with a seed that caused them to fail.
