value emitVerilog is not a member of circt.stage.ChiselStage

Hi
I got trouble to generate verilog, i got this error:
```

```
new ChiselStage().emitVerilog(new Hello);
```

```
scalaVersion := "2.13.12"

scalacOptions ++= Seq(
"-feature",
"-language:reflectiveCalls",
)

// Chisel 3.5
// addCompilerPlugin("edu.berkeley.cs" % "chisel3-plugin" % "6.0.0" cross CrossVersion.full)
// libraryDependencies += "edu.berkeley.cs" %% "chisel3" % "6.0.0"
// libraryDependencies += "edu.berkeley.cs" %% "chiseltest" % "0.6.0"

val chiselVersion = "6.0.0"
addCompilerPlugin("org.chipsalliance" % "chisel-plugin" % chiselVersion cross CrossVersion.full)
libraryDependencies += "org.chipsalliance" %% "chisel" % chiselVersion
libraryDependencies += "edu.berkeley.cs" %% "chiseltest" % "0.6.0" % "test"
```

thanks

Start with Hello.scala around line 35 and the ChiselStage API referenced by the compile error, then compare it with the Chisel 6.0.0 dependencies in build.sbt. Verify the relevant API and run the sbt compile or Verilog-generation command; done means the example compiles and generates Verilog without this error.
