transformer: differentiate import {} from "a"; and import from "a";

[Boshen]

Our AST differentiates import {} from "a"; and import from "a";

Failing babel test cases like imports/elide-no-import-specifiers/input.ts

Added failing test cases: https://github.com/oxc-project/oxc/pull/3735/files#diff-0a1b8e143f74590ed69ad0ad7abfcf2add6d7e6a9c3daff2bbb132b71e0f3f14

Do we want to distinguish them? Is there any semantic difference?

TypeScript seems to treat them differently: TS Playground
