compiler: Fix CPP guards around ghc_unique_counter64

The `ghc_unique_counter64` symbol was introduced in the RTS in the
64-bit unique refactor (!10568) which has been backported to %9.6.7 and
%9.8.4. Update the CPP to reflect this.

Fixes #25576.

Fix :info pretty-printing of UNPACKed fields

This patch:

* Ensures that we do not pretty-print a field like `foo :: {-# UNPACK #-} !Int`
  as `foo :: ! {-# UNPACK -#} Int` (as we were doing before) when running the
  `:info` command.
* Prevents coercions that arise from `UNPACK`ed fields (e.g., such as when one
  unpacks a newtype) from being printed in `:info` output unless `-dppr-debug`
  is enabled.

Fixes #25651.
