Resolves a bad false negative and a false positive Previously, for `D = dict[str, str]` we would require a type annotation for `d = D()` and we would fail to error on `D(x=1)` Fixes python#11093, fixes python#11246

Description
Fixes #11093
I explained what I analyzed about the issue in the comment #11093 (comment), so I would appreciate if someone could take a loot at it together with this PR.
Clearly, my fix is nothing but a workaround for the specific case in the issue, but surprisingly there is no regression in exisiting tests. So, I made this PR anyway as a starting point to ask some opinions about the issue itself. (Also, maybe CI will show me some regression).
It's highly likely that I'm missing some important use of
SemanticAnalyzer.translate_dict_call, but I couldn't figure it out by myself.Thanks a lot for the review!
Test Plan
I added new tests in
check-type-aliases.test:testTypeAliasDictNoVarAnnotatedError,testTypeAliasListNoVarAnnotatedError.I think the relevant existing tests are mostly in
check-typeddict.testand especially this test case:testCanCreateTypedDictInstanceWithDictCall.
