Implement code actions for `class X needs to be abstract` that implements all missing members

[rochala]

Compiler version

3.nightly

Minimized example

trait Test:
  def name: String
  def id: String

class TestImpl extends Test

Output

Diagnostics:
   class TestImpl needs to be abstract, since:
     it has 2 unimplemented members.
     /** As seen from class TestImpl, the missing signatures are as follows.
      *  For convenience, these are usable as stub implementations.
      */
       def id: String = ???
       def name: String = ???
     

Expectation

Code-Action properly implemented in dotty that allows us to implement all missing members. Also applicable to other issues similar to this such as try importing ...
