JavaParser is skipping some annotations that ClassfileParser is picking up

[Kordyjan]

I've encountered this behavior while I was testing #10751. When Test_1.scala name is changed to Test_0.scala here, the test started failing. It seems to be caused by JavaParser is skipping some annotations.

Currently, the JavaParser in dotty only parses annotations without arguments. Maybe we need to port this part from scalac.

Maybe we need to port this part from scalac.

That is my current plan.
