At this point there are a number of Flow features that the Esprima parser doesn't support. Rather than switch to the Flow parser ad hoc for those test cases, simplify by just using it systematically.
Use the same solution already present for ObjectTypeInternalSlot. This doesn't feel super clean -- plus, it'd be nice to unify with ObjectTypeInternalSlot, since that's so similar. But it doesn't seem materially less clean than the existing logic here, and it works, so it's a step forward for now.
I started by converting this test to a round-trip test with the same source code verbatim, just intending to make the test simpler and easier to read. But then it turned out that that version failed, because this code doesn't parse as this tree! It parses as something wacky, which spits out wacky output. And in fact Flow itself doesn't accept this code; it gives a series of parse errors. Instead, write a version of the code that Flow accepts (at least as far as parsing it -- it gives a later-stage error saying it doesn't recognize these particular internal slots), mainly by saying `declare class C` instead of `type A =`. So this version is not only simpler but more correct. Also add a few more cases that weren't covered in the previous test. Now that it only takes one line of code per case, it's easy to be thorough.
…ternalSlot This makes the logic for each of these less vulnerable to missing some functionality that was added for another one. Some of these features never appear in some of these cases; for example, indexers can't be optional. But when absent, they're harmlessly ignored.

Also make some infrastructural improvements to the Flow-related tests which I spotted along the way.
This adds a
@ts-expect-errorbecause of a property that's missing in ast-types. I've sent benjamn/ast-types#755 to fix that, so it'll naturally go away after that fix is merged and Recast's dependency on ast-types is updated to use it.
