Chisel 7.0.0-RC1 and Intellij errors

[kazutomo]

I'm trying out Chisel-7.0.0-RC1, and looks good so far, except the Intellij error messages.

While my Chisel code compiles without issues, Intellij shows "No implicit arguments of type: SourceInfo" (e.g., after IO), which is a bit annoying. I didn't see such error message with Chisel 6.7.0 or earlier.

I can suppress the error message by adding: implicit val info: SourceInfo = UnlocatableSourceInfo

But my question is: in Chisel 7.x, should we define an implicit val outself?

I'm also having this problem with Intellij IDEA reporting errors:

No given instance of type chisel3.experimental.SourceInfo was found for parameter sourceInfo of method IO in class BaseModule

and

Scala 2 macro cannot be used in Dotty. See https://docs.scala-lang.org/scala3/reference/dropped-features/macros.html<br/>To turn this error into a warning, pass -Xignore-scala2-macros to the compiler

These errors will occur everywhere the Module is used.

I tried to roll back the code on the chisel main branch and I found that this pr was causing these problems: #4768

It seems that we may need to make some fixes and adjustments.
