repr produces invalid code for typed lambdas

[timotheecour]

Example

macro deb1(a) =
  echo a.repr
macro deb2(a: typed) =
  echo a.repr
deb1:
  (proc (): auto = 12)()
deb2:
  (proc (): auto = 12)()

Current Output

(proc (): auto =
  12)()

proc (): auto = result = 12()

Expected Output

(proc (): auto =
  12)()

(proc (): auto = result = 12)()

It would be very tedious but the way to fix this is to define a list of node kinds that have less precedence than call parentheses i.e. sym nodes, literals, normal calls but not commands or operators etc. then wrap them in (). You also have to skip nodes that aren't rendered like nkHiddenCallConv.
