Synthetic top-level <init> member causes Types.member to crash

Causes #16650, can cause other problems in the future. For now, #16550 is fixed with a workaround. 

## Compiler version

`3.3.0-RC1-bin-20230109-f56089b-NIGHTLY`

## Minimized code

`LinearMap.scala` file:
```scala
//> using scala "3.3.0-RC1-bin-20230109-f56089b-NIGHTLY"
package repro

val z = 3
```

`LinearSet.scala` file:
```Scala
//> using scala "3.3.0-RC1-bin-20230109-f56089b-NIGHTLY"
package repro

val x = 2
```

Compile two above files in separate run, and *put them in a jar file*. Breaks only if the classpath in the snippet below is a jar - does not work with a directory of class and tasty files.
```
scala-cli package --library -o out.jar LinearMap.scala LinearSet.scala -f
```

Then, compile a Macro and a file calling this macro:

`Macro.scala` file:
```Scala
import scala.quoted.*

inline def foo = ${ fooImpl }

def fooImpl(using Quotes) =
    import quotes.reflect.*

    val x = Symbol.requiredPackage("repro")
    val y = Select.unique(Ref(x), "<init>")

    println(y)

    '{}
```

`Main.scala` file:
```Scala
//> using scala "3.3.0-RC1-bin-20230109-f56089b-NIGHTLY"

val x = foo
```
Run these files with dependency on the jar:
```
scala-cli compile Main.scala Macro.scala -cp out.jar --server=false
```

## Output

```
-- Error: /**/repro/Main.scala:3:8 
3 |val x = foo
  |        ^^^
  |Exception occurred while executing macro expansion.
  |dotty.tools.dotc.core.TypeError$$anon$1: Toplevel definition <init> is defined in
  |  /**/repro/out.jar(repro/LinearSet$package.class)
  |and also in
  |  /**/repro/out.jar(repro/LinearMap$package.class)
  |One of these files should be removed from the classpath.

```

## Expectation
No error

## Stack trace at crash
(at #16650 the scenario is very similar - the member function is called in the same scenario )
