Allow with-chain wrapping for all params #1125

[iantabolt]

Back to #1125, this covers parameter types for with-chains.

Currently,

class NeedsServices(
    services: Bag
      with SomeOtherService.RequiredServices
      with HasDynamicConfig
      with HasThrottles
      with HasThrowableNotifier
)

ends up as

class NeedsServices(
    services: Bag with SomeOtherService.RequiredServices with HasDynamicConfig with HasThrottles with HasThrowableNotifier
)

With this change it will wrap it as expected with one with per line.

LGTM 👍 Thanks!

I wonder if we hit a regression by simply removing this guard 🤔

[olafurpg]

Just tried and it didn't come out great, need tree printer to properly fix this

[iantabolt]

Yeah I tried removing the parent guard when playing around with my original PR and it ended up wrapping after the second with sometimes. I was thinking you need to at least make sure that parent is not another Type.With but TreeOps.topTypeWith should guarantee that 🤔

Life is a lot easier in https://github.com/scalacenter/scala-syntax where we print code by traversing the tree instead of visiting the parent chain up from tokens as we do here.
