Jake Leahy ef5ab2fc51 Fix getTypeImpl not returning defaults (#25592) 
`getTypeImpl` and friends were always putting `nkEmpty` in the default
value field which meant the default values couldn't be introspected.
This copies the default AST so it can be seen in the returned object

(cherry picked from commit edbb32e4c4)

Nim Compiler

  • This directory contains the Nim compiler written in Nim.
  • Note that this code has been translated from a bootstrapping version written in Pascal.
  • So the code is not a poster child of good Nim code.

See Internals of the Nim Compiler for more information.
